I hope so too, but Bungie tried somewhat with Reach, and it has been the most polarizing of the series amongst the community, particularly the multiplayer. Microsoft has paid no expense putting together an all-star development team, I just hope their not creatively stymied to stick to the current formula. I'm expecting them to play it fairly safe in terms of gameplay and really listen to a lot of community feedback, reverting back to more of how the game played online in Halo 1-3 (i.e. no reticule bloom, armor abilities). Maybe they will change things up more for single player, at least it's going to be cool to see new enemies. Tough to fill Marty's shoes, but Neil Davidge (the composer and producer for the last few Massive Attack albums) being teased as the composer for Halo 4 is exciting.
