PS4 System
Still undecided on which games to pick up on launch day with the exception being the games provided by PS+ (Driveclub and Resogun).
I think I'll likely upgrade Driveclub. The more I see of Killzone, the more I want it. I was originally planning to pre-order just BF4 and Watch Dogs but I'm playing more of a waiting game on both at the moment.
Basically it is hard to see at this exact moment in time, since we only know 'launch window' and not 'launch day' games. I get the impression quite a few third party games won't be able on launch day (such as BF4). I'd also like to see a few reviews for certain games as well before purchasing.
Either way, there is definitely quite a few to choose between which is why I'm finding it tough! There are so many coming out around that time.
EDIT: One other factor - we still don't know the price difference between digital titles and retail for the PS4.
