I dont see a single change or improvement being announced for CFB 26...but they took time to prepare a corny video to ask for early purchases.
I have already gone on record as saying I will likely buy the game. I will not purchase now though, when they haven't done anything to earn me buying it.
I have been offering grace for ridiculous issues with things like Champs not registering results, suggesting all hands were on deck to make 26' even better. I would still like to think that, but with no announcement about the actual game, it makes it hard to do so at this point.
