While in EB today I discovered to my surprise that Saints Row 2 was in the "Coming Soon" section for PC. I know this game will probably not touch GTA IV quality, but like previous releases of GTA games on PC, they crapped all over the console versions in controls, visuals, customization etc.

Thus this could be good fun to fill in the time waiting for a PC version of GTA IV (if it will come to PC of course)
