Knowing CapCom, the Wii U game is going to be an easy port or a cheap spin-off. Something in the Resident Evil series seems likely, since that appears to be a franchise that has sold decently on Nintendo systems in the past.
Also, I noticed they didn't say a new installment in the Monster Hunter series for 3DS, so it is likely to be a port of Monster Hunter Portable 3rd on the PSP.
