I still play ps2 games as well as ps1 games.
Yes I would have kept my ps2 but the hassle of having two systems 2 different discs for the same game is a bit ridiculous. Say I wanted to play madden 2012 I would have to hook up the ps3 just play it or hope that Sony makes a copy for the ps4 and get raped for having to buy the game twice. I figure they would at least give the option, just like HD sizes. I'm guessing the new Discs/games are gonna $70-$80. so they are really hosing the customer/fans. I wouldn't buy and xbox and ps3 to play the same game, why would i do it with 2 playstations? We will have to see what the retail value of the new ps4 is when its released to determine if its worth buying.
So when the new system launches and the price drops a year later, what would say the reason for price drop would be? They can't say its because of there is less components(backward compatible). I was a huge supporter of Sony before the ps3. After not so much, now with the new ps4 I may just give up the games all together and spend my money on something for the civic.
