I agree with Pyro (somewhat). WiiU's gamepad (it's main selling feature) is too complex for casuals and too WiiU is too casual for core. Nintendo has put themselves out of an audience except for diehard Nintendo fans which gives WiiU sales of 20M tops (similar to GC).
Unlike DS/Wii there is nothing really original about WiiU. Touchscreens are in almost every house already. Asymetric gameplay? Had that with GC (PacMan Vs and others with Gameboy connection). DS had innovative games like Nintendogs/Brain Age to bring in new audiences. Wii had Wii Sports. WiiU so far has nothing of the sort.
I disagree about no Asymetric game hitting 10m. NintendoLand will. Probably the only one though.
Next gen is Microsoft's to win (or lose). A more powerful Kinect with a well executed plan will steal the casual market and MS is capable of keeping the core. MS problem will also be to come out with truly innovative gameplay to truly excite people about the new Kinect. I expect Sony to continue with the losing path they've been following with PSP/PS3/PSVita. More power. Fewer sales.
