I was kinda bothered by the the crew's comments on how the games need to be more standardized. If at this point, you are already getting tired of the formula, imagine how bad that would be if every CoD had exactly the same stuff as the last. While I understand Jeff's dislike of zombies, I also think it's a little unfair to expect two studios that are run totally separately and produce games separately to just take a single side and go only with that. I feel like it would be better if there was MORE separation with MW and Treyarch CoD, because it seems like when they pull away from MW things, not only do they extend the lifetime of the franchise by preventing the series like really feeling like an annual series. While the gameplay core is kind of similar, I feel like MW2 and Black Ops are in a lot of ways, wildly different, particularly in setting and story telling. I think it would have been a mistake to have spec ops in Black Ops because that would be bordering on feeling like "Hey, we made another game like that game that came out 12 months ago." 
I find it odd that these guys often do the thing of saying "Well, this whole formula is starting to get old" but when they don't keep the formula even more familiar, they complain yet again. I don't think it is petty to say "Hey, we made zombies and it was super popular in our game, lets do that again." And I'm willing to bet at least 50% of the people wanting this game wanted Zombies, if not more. I feel that if anything, it's more petty to take the features of the other teams stuff just for the sake of selling better. Zombies is a quality mode, just as well made as Spec Ops, and at least as popular. 
Don't get me wrong, I really enjoyed both modes, and all of the things that made MW and Treyarch CoD their own things, I don't favor Treyarch at all, they have made bad games, but I feel like with Black Ops, they have shown that they are capable of making their own goddamn game.
