I would have gone PS4, but not waiting that long. GMG pre-order is a go.
Much as I loved the first one, still perfectly happy to wait...
I haven't really read up on this game much, but if it's anything like the previous one, I'm likely going to want to Platinum it on the PS4. I'll probably skip the PC version as a result. Getting 100% on PC felt like a waste when I couldn't get the platinum for it.
