Eh, maybe. GTA started on consoles but GTA 3, VC, SA were excellent on the PC (if not better). Now GTA IV was a bitter disappointment for the non high-end PC gamers but I still have faith in Rockstar that they'll learn from this mistake of theirs.
Yes there is hope. But then you remember that apparently Read Dead Redemption was such a hopeless mess that they couldn't get it to work on pc properly and gave up trying.
Of course there are other things that give us hope this time. Like the fact that people have found pc config files in the xbox 360 version.
