PS4 wont be this year. They'll announce it & possibly show a case, but the hardware's far from finalised. They'd have to have it in full production by early spring for a Winter 2013 release, and after the fiasco with the PS3 they're taking the smart route & not rushing.
Plus Sony already confirmed the PS3 was going to have 7 year minimum before a new machine so it'll most likely be fall 2014 if they decide to keep to that.
To answer the OP, depends on how much stuff you've got for it & how much you want one. If you've got a large collection then replacing the machine would make sense.
