I just got a PS2 again not long ago from my girlfriend. I definitely had a lot of fun playing it back in my younger years. I still love it, and plan on starting up a PS2 collection of games, etc.
I can see why they'd stop making it though, I'm surprise that they've been making them for 12 years, they're hard to find in Canada now usually, only available at pawn shops.
I hope the PS4 (Orbis) can play PS3 games, but I highly doubt it. I think they're going to go a whole different direction with the Orbis, and Playstation will be just history.
