it depends...where are all of sony's exclusives going to go after the ps3 is discontinued? There's probably 8+ that I can name (killzone 2, FFXIII vs, infamous, uncharted 2, ratchet and clank sequel, GT5, Heavy Rain, MAG and god of war 3 + all the psn games). What will happen to those studios making the aforementioned games also?
I'd probably keep it as a blu-ray player and for the games I have as of yet played. I'll keep playing my ps3 until I've run out of games to play and then simply use it as blu-ray player.
Not sure what else to say really but 'what i would do' would ultimately pend on the future games and where the ps3 exclusives will be going?
But in all honesty I can't see it happening...discontinued? SCE shutdown? a little bit too far fetched in my opinion...so obviously shock and dissapointment would be my initial reaction and probably sadden that there would be less competition in the console market, and obviously about the amount of jobs lost.
Apart from that, I'd probably laugh that the sony haters wouldn't have the ps3 to bash as their main hobby lol
