Will it have improved support for spectating, tournaments, etc.?

I hope so. Autosport had some really cool features with the 2nd-screen race positions and minimap, but it was hard to screen-cap that for livestreams. Also, having to enter the race as a driver, and then slam into the side-wall and retire for a spectator camera... was cumbersome at best. Initial signs prove hopeful overall for this new GRID title, but I look forward to when CM is ready to reveal more information on this particular subject.
