A lot of questions remain about what Rockstar intend in supporting PC gaming, and I think based on GTA IV offspring using the same engine for it, this game should be coming to PC at some point.
Someone posted on Rocks' site that nVidia got the contract to make a PC version of GTA this time around, as interesting as that sounds, it makes little sense! haha
