What should i do with my PS3 if the ps4 comes out?
Keep playing on it because the new one is too expensive and has fewer games?
Sell it on Ebay ;)
Gamestop gives a trade in for old systems. You'll probably get $50-$100 trade in value for it towards a PS4. I plan to do that myself.
I would keep it.
you should keep it, this way you could play certain games
Sell it when the news comes out that they are making a new one.
Get an Xbox
Depends on how much the newer consoles will cost
the new one sucks the games u buy can only be played on your console and u can't sell them to game stop or anyone else if u were u I would go with the new Xbox that's coming out
