I never had PS3 and I am planing to buy PS4 in one point (waiting for one more hardware revision and price cut) so I am pretty interested for remaster for PS4.
Sony already said more remasters are coming. We already have The Last Of Us, Good Of War 3, Jorney, we will have Beyond: Two Souls, Heavy Rain and Nathan Drake Collection.
I think it's pretty obvious that Sony will consider only 1st party titles.
What do you think realistically what exactly remasters could we see on PS4?
I think/hope they will bring Shadow of Colossus and Ico, I would love Puppeteer too.
