Its not too early at all. Developing for Wii is quick and easy. Also, why would it be too late to release in 2011. Given the 6yr cycle 2012 would be the year of a successor for Wii, but the 6yr cycle is probably to short for this gen. They could start this year in autumn and probably have a Wii GTA ready by christmas 2010 or march 2011. They could always re-use the engine and assets from the ps2 era GTA's.
