Yeah dude. MAG is doing the same old same old. 64/128/256 player battles, persistent battlefields, player skill trees, squad buffs, special officer abilities, multi-objective gameplay, special dedicated servers/netcoding, we're all tired of that stuff on consoles. What we want is the more fresh experience that we're probably going to get with Call of Duty 6: Modern Warfare 2. I don't think they're going to risk straying far from their formula, which is fine, it works. But they may get passed by another game that's wildly more ambitious than "what we know of MW2", which is nothing, but for now we can go off their old work.
If Zipper pulls a Slant 6, yeah, MAG is going to fail hard. If they deliver, I'm not so sure how you can be so assured that their best won't be better than IW's efforts. They're both skilled devs, one is going to be riding their last success waves yet, another is a 1st party dev with lots of backing focusing on one experience on a single machine.
