If they made a controller it would be like reversed Wii U and have potential btw, as long as you could connect it to any ol TV without issues. Then again, it's not gonna be competing with the current gen consoles for long, soon enough they'll be last gen (of course, the Wii U might not be capable of that much better graphically, though we don't know that yet, and it does have Nintendo software). If they did do that, I could definitely see it take a good segment of the market and pave the way for future iterations to do more than that, if they were actually willing to support it for a good chunk of time without making it obsolette with newer iterations (the iPad2 came out in 2011, now we're getting 3 and the big name graphically demanding games like this are already dropping 2) and with potential for gradual price dropping like consoles get since it's basically PS3 launch level pricing.
I doubt they'll do any of that, which is pretty shortsighted sadly, they could benefit from that approach without harming their image with people who aren't interested at all. It will probably be capable of running a current COD just fine, why not capitalise on that capability considering the vast audience for such games. Of course they wouldn't steal all the fans but there are many who would buy it for an iPad3 they'll get, solely or as a double dip, if they don't sacrifice controls and can play it on and off their TV.
