Nope, not buying one nor have I bought any Sony hardware since the original PS1.
Nintendo has it right IMO for this generation. No super high res, 480 p, easy to use development tools. no multi core processing, new controller tech (they were first with the d-pad, analog stick now the gyro controller) and a back to the basics fun that video games are supposed to have.
Games have become way too bloated due to an emphasis on graphics over game play.
There were a handful of titles that were really unique on the PS 2 but alas that did not make me want to buy one.
Gamecube had a ton of unique titles (mainly from Nintendos in house developement) which for me drives the sale of the hardware.
