Generally I get more selective about which new releases I pick up by this point, having bought all three platforms near debut with the exception of the 360 (fall 07).
I will still pick up games that caught my interest on a good sale, but the longer a platform's been available, the more quality games there are to choose from and that leads to the inevitable backlog/pile up of unplayed or barely played games.
I'm pretty much done with the Wii. I don't play any of the games at all, and I saw this coming in 2009. No More Heroes 2, Metroid and Zelda were the last of the titles I wanted to play. I barely played NMH2 and MoM was a bust so it's Zelda and done.
The 360 still has Gears 3, but after the disappointment of Gears 2 (never bothered to finish), unless the game is universally rated "M for Magical" it's not getting my $60. Platinum Hits $30 or nothing. Everything else is multiplatform, which means unless the 360 version is better than the PS3 version and the PC version is somehow screwed up, it will be mostly cricket chirps playing on my Xbox for 2011.
That is, unless Kinect gets its first legitimate killer app that isn't Chuck E Cheese style fun for the entire family...
The PS3 is my default media and movie player. It gets any multiplatform that doesn't run better on the Xbox that is also somehow gimped on PC. It happens. SCE IPs have been heavy favorites this generation with several good ones in the pipes for 2011. It won't be boxed until I either stop watching movies or I buy a more convenient media player/BD player.
As far as PC goes, there are no "generations" to speak of and you never stop using it. About the only dust it collects is whatever junk it Hoovers in through its fans. You upgrade video cards when either the performance of the latest hardware crushing game you *must* play doesn't play acceptably (depending on your personal standards for performance), or when you catch a deal on a better video card that is simply "too good to pass up."
