OK so I really want to play 'The Last Of Us' but I don't have a PS3 but now I want a PS3 so I can play 'The Last Of Us'. Do I wait until the PS4 is out before taking the plunge? Some PS3s seem to be going reasonably cheap on eBay. I don't really want to pay more than £50 for one though. Is the price likely to drop much when the new machine is released or should I just take the plunge now?

Also, recommend me some other good PS3 exclusives I can pick up relatively cheap.

yes, it's another gaming thread because I'm a grown-up and can do what I like

PS. Haven't owned a console since the original Playstation.
