I'll move onto Bungies next thing. Halo is one of the best games/trilogy/series ever created, but we all gotta move on sometime.
And I do believe Halo 4 will "fail". They have been hyping it up way to much with "Halo 4 will be pushing the envelopes on Visuals, gameplay, and campaign". Are you serious? I HIGHLY doubt 343 is "pushing the envelopes" for all that, not to mention the fact the game is coming out in around 9 months, and we haven't heard a single peep about the game, other have then saying its going to be the most amazing game ever.
