The touchpad has to be there for BC, you can't pack in a controller that's missing features from the previous one if your console is supporting the previous gen of games.
A screen that small would be useless in madden, you wouldn't be able to read anything and good luck picking a play using your fingers on something that small. Just go by the honor system when playing vs someone in the same room like we've all done for decades lol.
I like the idea of it, but in reality I have to agree...I really don’t think it’d be practical for most games. Plus as mentioned, it would just drive the cost up.
