I think il go with 2 Snipers and 2 heavies and 1 support and 1 assault.

This will maybe be a team build that will suit someone that want to take longer time with the game. maybe setting up a enemy with suppression fire and then snipe em or something im not entierly sure yet. But il be sure the try different things when the game comes out.

I'm kind of loving on the assault troopers, so thinking 3 assault, 1 sniper / 1 heavy / 1 support. But no plan survives first contact etc.

after playing the hacked demo I definately see the usefullness of heavy assault builds. However . . .

. . . so rookies will always be in the squad to take point. In that sense this game will be just like the original.

Also, I read about heavies getting a perk on their 3rd level that allows them to shoot twice if they stand still or fire and then retreat. Very useful tweak to the normal movement mechanic. These kinds of tweaks are what I'll be looking for my alpha squad composition.

Bottom line tho . . . squad comp will depend on mission type, mission difficulty and map type.

All that said, here's what i've theoryhammered for initial squad deployment:
1 sniper, 1 heavy, 1 support, 2 assualt, 1 rookie

I like the addition of bullet sponges :D

Sniper, Heavy, 2 Assaults, Support and Sav

I would take the Sav mainly to check how good it is, if it will become useless at the later missions I will know by then what other class i would need.

Also would give Rifle and Shotgun to my Assaults. To have both Close combat and Range skills.

I like to change the team a lot,so:
2/3 assaults, 1/2 support, 1/2 heavy/sav, and ofc 1 sniper.
From all the vids, it look like these minitank(sav) have some actually use(unlike in the original xcom).
Also from all the vid, it seem there is allways be CQB at everymission, so shotgun is a must have(even as I like to take out enemy from long range).
And because team max out at 6. So no more rookie scout. Unlike in the original, few rookie die is "normal" in that.

i think i will chose troops depending on what the mission need me to do is it a terror mission for example i dont think i will use a sniper

Terror missions need snipers too (taking down aliens that threaten to kill civilians next round is very important).

I usually go 2 assault, 2 snipers, 1 heavy and 1 support for almost all my missions.

My first playthrough (normal) I was able to rock 2 heavies, 2 assault, 1 sniper, 1 Support to great effect. One of my assault trooper and one heavy had the gift also, so that was nice in the end.

To OP, I used that exact build on my first CI playthough and had no problems beating it. Late game snipers are super powerful so you don't need more than one (my sniper had more than 120 kills by the end of the game) and having two heavies with heat ammo made cyberdisks and sectopods a breaze. I recommend equiping atleast one of the assaults with a rifle for the range and train up a backup support medic because if you don't and your support gets killed in a mission late game you are in a world of hurt.

I usually go 2 assault, 2 snipers, 1 heavy and 1 support for almost all my missions.

It depends on the mission obviously. Terror sites with chrysalids, I'm bringing 2 heavies and 2 assaults at least and lots of grenades! Mission with ethereals? No rookies allowed and I'll take anyone with psi abilities with high will (and psi inspiration skill). Run of the mill ufo crash/landing site? Extra heavy if there is a beserker, otherwise mostly low ranked guys to improve there levels. And always a sniper.... always. Massive damage from them.

My latest Team i won on classic Ironman was 2 assault 2 supports and one heavy and sniper
The heavy in 2nd row to assist with rockets and holografic assist and 2 assault which can cover eachother if the Run and Gun brought one in trouble. 2 supports with one having smoke specialisation and one on medic. So if either of the 2 is unable to fight, people still can be revived and saved. And Smoke...you can t have enough on higher difficulties! The Sniper savely staying in the back, picking out heavy targets like Sectopods which can be killed in 1 Round if all is doing good. In the whole campaign just 2 guys died (1 in the End).

I prefered a 4 assault (each armed with a arc thrower in the early phases for live capture of aliens, later with nanofiber vests for extra hitpoints), 1 heavy (for the rockets) and a support (for the 3 medipacks) because the assault class allows the run & gun, double shot and the reaction shots in close range and with the right weapon and armor loadouts (scatter lasers/later alloy cannons prooved their worth even in the temple ship, and the titan armors gave them some toughness for some really insane BAAANZAAAII! level attacks so they could take a few hits and still finish the enemy) they are just the best for my taste of 4 men charges. The heavy is a rocketman and used to weaken enemy groups before the assaults move in. the support medic is a must to heal/revive those who got hit in the charge, so he usualy stays back in safer ground behind some covering terrains, or escorts the heavy as rearguard. well - thats my favored team setup; as for armor preferences, I like the titan armor because they give the guys a little "warhammer 40000" space marine look with a helmet;

I like to run with 2 assault, 1 support, 1 heavy and 2 snipers. I might substitute a shiv for either an assault or a heavy, especially once you get hover shivs. I found the snipers become even more effective when you can get archangel armor. I put them in flight in the back on overwatch to protect the assaults as they go forward. If you don't move them and just let them hover, they don't use any fuel. The heavy is for the rocket launcher; either to take out groups or very tough enemies, or to punch a hole in a building/ship. Finally, the support is the medic of the group. He also acts as an extra overwatch when wearing archangel armor.
