And it will only get worse from that point.
I never quite understood the mindset of "Right. That's it. I'm bored waiting for a £40 game on the £300 console I have, so I'm buying a £200 console and £40 a year for the online service just to play a different £40 game!". Congratulations. Hope you enjoy it and all but... seriously, who on Earth would throw that much money away for one game on each console and why?
Not to mention the fact that the PS3 has been out 3 years, not 5, so unless you have insider information that says GT5 won't be out until 2012 (and I'm not ruling that out), that'd be an exaggeration at best.
