Well they've been showing gameplay stuff off since May, multiplayer anyways. They've released some campaign stuff too but mostly a glimpse here and there, they're trying to keep that stuff a secret. Halo has always been asked to do more Live Action stuff tho...prolly cuz people have been wanting a big budget Halo movie for a decade now. This and the Forward Unto Dawn series on Machinima right now might be a hint that they're working towards that thoUrgh, live action game trailers. I'm sure it's very nice but if a game trailer doesn't show the game; you've lost me as a customer.
Won't ruin too much for ya, but basically the Forerunners are involved, a faction of the covenant might be up to no good, Flood is gone (at least from what we know so far) and Cortana is feeling the effects of rampancy now that she's past her 7 year shelf life. Lotta crazy stuff is gonna go down in this new trilogy, and also the multiplayer is now filled with lots of Battlefield 3/Call of Duty/Gears of War type loadout systems. Classes, perks, whatever u wanna call them will now play a role in Halo's multiplayer options.I'm rather intrigued. What is the new enemy? What is the covenant up to now? I think I have to get the game to find out
Further evidence that Hollywood is running out of money but the games industry is printing it
