Since CDP announced Witcher 3 was coming to PS4, should they release Witcher 2 on PS3 via PSN. I'd love for them too since I bought Witcher 1 and don't own Witcher 2 yet.

Porting to the PS3 is said to be more difficult than porting to the Xbox 360, so by the time they'd finish, the PS4 would be out and all their work would be for a system that no one cares about anymore. It would be a hugely stupid business move. Especially since PSN titles apparently won't transfer over to the PS4.

I wouldn't hold my breath if I were you.

There's no need. Seriously. CDP announced that you'll be able to transfer your save file of the PC versions of both The Witcher and The Witcher 2 to PS4. So far, there's not much details as to how that'll work, but it has been confirmed. So for those who previously played on PC and want to change up - they could do just that, and that's what I may do. The only way to play The Witcher 2 is to get the PC version, I assume your PC can't handle it. Well, if that's the case, then I'm sorry.
