I know i mentioned this before but now with 3.6, there is no promise of ever breaking it. And the good game coming out this year for ps3 only:
Infamous 2 ( want it)
Tales of Grace F ( want it)
Uncharted 3 ( Definitely want it)
Twisted Metal ( Want it)
+ a couple more
Now i am not sure if those game are worth giving up jb for..... but it is definitely more than GT5...
