I envy you. Having the vast array of PS3 exclusives ahead of you. It's an easy decision IMO. 1) Get the next gen console and have to wait for the games you want to play or 2) get last gen and have a list of amazing, gen defining games out there just waiting for you.
Go grab yourself: TLOU, Uncharted 1-3, Heavy Rain & Beyond, GOW 3, Demon's Souls, 3D Dot Game Heroes, Folklore (if you can find it), Resistance 1-3, Puppeteer, LBP1 & 2, Infamous 1 & 2, Heavenly Sword, Ico & Shadow of the colossus Collection, Journey and Ni No Kuni... and thank me later.
