When will a game use two Wii U Gamepads?

I honestly think they said it will support 2 gamepads only to stop the bitching... having another gamepad will cut the performance by half so unless they are gonna magically teleport better CPU/GPU in our wiiU's, I dont see that happening

we're all very used to 30fps so no body would mind. it's really a matter of getting the attach rate high enough.

Are you saying the gamepads are usually 30fps?  Or that the games on the TV for the Wii U have been usually 30 fps?

I read somewhere that two Wii U gamepads running different images would cut a 60fps game down to 30fps on each screen. But I think that's not a big deal. I'm fine with it.
