I want White Glint's emblem on my arm.
Anyway, from what I've seen, the engine is pretty similar to Future Soldier, but with more augmented-reality capabilities, and less blue.
Cover WILL be varied, I feel quite sure, if this is anything like it's predecessor at all. Not to mention that, considering Ubisoft's focus on connectivity between players and the fact they haven't fucked that up (yet), if that feature goes down well, then the whole experience should be like a console DayZ minus the zombies, instead you get AI soldiers (probably the "cop rescue" scene- note they didn't say anything such as "player group" or "other player" such as in the last bit of that). From what I remember of GR:FS, the AI isn't braindead, although it might be somewhat problematic in the areas of seeing you before someone shoots. That may have just been the stealth aspect of the original though, as they weren't supposed to see you and you were invisible but anyway...
If the community is anything like GR:FS, we aren't going to see the same levels of CODfaggotry prevalent in today's shooters.
From what I can see, there will be AI soldiers, probably events that you do like the cop thing that regenerate, possibly as different things, over time, and other player-groups who will want to loot your shit. What I don't like about the game was Chris. Chris was the tablet drone. I don't want to have that, because I still like piloting drones myself and I don't want to have to boot up a tablet I don't own and not be able to still play the main game.
I trust Ubisoft with my money, especially with Tom Clancy titles. I didn't say I BLINDLY trust them, though.
