I don't know why are you arguing. PC gaming is dead so if you are gamer - you have both consoles and have no problems with playing GT 5
I have been playing on PC since 1990, but around 2005 I realized that there is simply nothing to play anymore. Pretty much every famous PC series and even genres died out.
That's because 99% of PC games are a console ports ever since the 360 was released. Publishers identified their primary market as the one which has potentially the most customers.
The PC is easier to develop for technically, but much more difficult to support because of the billions of different configurations. Crysis is a good example of why the PC market is so difficult: They made it for machines that didn't really exist yet because they wanted to push the technology and make it 'futureproof'. Of course, this meant that they vastly reduced their potential market, because while the game can run on much lower spec machines it just didn't look good enough. Hence Crysis was pirated so much and sold relatively little, though it did make its costs back (and then some).
This is a catch-22 for PC developers, technology-wise. Make it look too good and you reduce your market because of the necessary hardware, make it look too bad and you reduce it again because it won't be viewed as a good enough game. On consoles this is simply not a problem at all because they are a proven, uniform system that has sold millions of times already - Your potential market is effectively bigger even though there's a LOT more PC's in the world.
With the advent of World of Warcraft and the 360/PS3, PC gaming went out of the picture not because there's no market but because the other markets are so much easier to sell products in.
Now, console ports are fine in theory, but rather than making the effort on properly adapting the game to the PC the developer usually opts for easy street, "making it work" to sell a few more games than he would have on just consoles, but nothing more. I have to think of an example of how to do it right: Mass Effect. The PC port was utterly brilliant, vastly improved on the 360 version. Bad example: Force Unleashed. Utterly bad port, 1 to 1 job just to make a few more sales, and sadly the latter is the standard lately.
PC gaming is not dying, not even by a long shot, but it'll take a while before developers stop trying to develop a one-time physical good and start thinking about a 'product' which isn't based on day-1 sales - Something people will happily pay a premium for. PC gaming has evolved into a different market than consoles a while ago, but that hasn't sunk in yet.
