Depends on whats going to get released after the PS4 launch.

But I know I will buy
Gran Tourismo
Beyond
The Last of Us

Atelier games that might still come out
Tales of xillia and tales of xillia 2
FFXIII: Lightning returns
Kingdom hearts 1.5 and 2.5 HD

After all these I'll feel OK about buying a new system.

You better start on it and give your pc a break. 

The Last of Us, Beyond Two Souls, GT6, Kingdom Hearts 1.5, GTAV, Tales of Xillia, and that is about all I can think of right now. Plan on getting Watch Dogs on Pc or Ps4, and Final Fantasy X & X-2 on Vita.

I don't know that yet as games for the system could be easily coming out in 2014...maybe Tales of Xilia 2 will be over by then?

GTA5 (if it doesn't get ported)
Puppeteer (most anticipated game of the year as the humor and art style look like they were made for me)
Tomb Raider (got it but haven't started)
Budokai HD (will get it this Summer)
Beyond 2 Souls (LOVED Heavy Rain and this looks super refined and more expansive)
Last of Us (it's ND need I say more?)

this is way to soon to say. there are tons and tons of games on the ps3. and there is still so much life left into it. i dont know what will be the last game i play or buy. its way to soon

it does still have plenty of life so let's enjoy the last few months of PS3 being the newest Sony home console and being at the forefront.  One thing is for sure Sony sure does give a lot more of a shit about their console in its 7th year than Nintendo or Microsoft.  Gears vs. Sly, GoW, LoU, Puppeteer, Rain, Guacamele, Beyond, GT6, and many more.  There's just no comparison.

PS3 support isn't going to end anytime soon. Remember the PS2.

Far too early to make any calls here.

Probably Last of Us.
