A lot of these games have been in developement for a long time and many have taken longer then they were most likely intended. Bioshock infinite has been delayed multiple times, Tomb Raider too... GTAV prob wasn't meant to take 5 years. They need as stable and safe developement as possible and throwing in a new console to port the thing too wouldn't help that at all.
I would imagine theyll all be ported later down the line provided the games themselves are successful and the Wii U has a good start.
