Back on April fools, Ron Gilbert made an announcement on his blog saying he was working on a new Monkey Island game. Despite Ron Gilbert always being vehemently against April fools, this did seem to be too good to be true.
But now, today, a trailer dropped for 'Return to Monkey Island'.
A game being developed by Ron Gilbert's own studio Terrible Toybox. The chances seemed slim after Disney's acquisition of LucasArts along with the entirety of LucasFilm studio's. Slimmer still after Disney shut LucasArts down, only to revive the game division as LucasFilm Games.

Strangely this game isn't being published by Disney, but by Devolver Digital, a publisher known for creative, high quality indie titles who generally let the studios do their own thing.
Ron Gilbert has always said he wouldn't come back to Monkey Island unless he had full creative control. And that seems to have been given to him now.

Return to Monkey Island will be a sequel to the games Ron Gilbert designed, so The Secret of Monkey Island, and it's sequel Monkey Island 2: LeChuck's Revenge.
Although a talking skull reminiscent of Murray is featured in the trailer, despite Murray only being introduced in The Curse of Monkey Island.

Along with Ron Gilbert, fellow Monkey Island designer/writer Dave Grossman and composer Peter McConnel are also back to lend their talents to the pirate adventure once again.

The trailer also confirms Dominic Armato is back as the voice of Guybrush.
As well as a releasedate sometime this year.

Not much else is known, but keep an eye on the website[returntomonkeyisland.com] for updates.
