The Wii U merges the gameplay opportunities of the XBox 360/PS3, Wii, DS/3DS, and Phone/Tablet into one device; and companies that are interested should be able to find gameplay mechanics from one of these devices that will enhance the gameplay in whatever game they're developing. The amount of things developers can think is infinite. If it fails, then I give up on the gaming community - you can have your 'apps' and I'll just stick with the deeper stuff that comprises generations 3-7.
Games can and should tell stories and share ideas through their mechanics. This is the intrinsic element of the medium and this is how experiences should be crafted in video games. No company does this as well as Nintendo and their echoes from the past.
