Same here .
My wii is still working ever since i bought it, it did not hit the dust with black ops . I hope that mw3 isn't the last straw...
My Expectations are pretty low this time after over hyping black ops wii. So I just expect Player card emblems this time hopefully and mic support and patching. I don't expect DLC at all but i can dream i guess.
My expectations would be for the devs to take into account every problem of the last 3 wii cod games and iron them out instead of rushing in like a mad bull in a china shop. For me a decent connection would make this game. Mwr was reasonable for me but black ops connection was totally bi polar. Weapons/perks won't bother me much as i'm mainly a HCTDM player so it won't matter what people use because in HC mode all guns work fine.
DLC? We could get new weapons instead of new maps if that'd be a version of DLC you'd be willing to accept. HVS did that in Conduit 2; here though I'm not so sure, I have to see more of the game to give a 'better' analogy.
