Considering that SE core titles usually take forever to develop, it's probably too late already. FFXIII was first announced 2006... Western markets will see it in 2010, that's four years!
Unless they're already working on it, I can't imagine they'd finish a Wii FF game this generation.
Bioshock... I don't know. Do you know what the problem is that 3rd parties are facing (in my opinion)?
Many Blockbusters are not that great once you take away the fantastic graphics. The shooter audience in particular is extremely graphics obsessed; a step backwards technologically is hard to sell.
GTA, yes probably. Take2 already called the DS GTA a test for a potential Wii version. And a GTA game would work fine, since the graphics don't have to be cutting edge realistic.
