I'll be getting my hands on a PS3, so Demon's Souls is finally going to happen for me. Maybe some other PS3-exclusives like Dragon's Crown, Playstation All-Stars Battle Royale, Guacamelee! and Journey?
Skullgirls on PC of course, but I'm on the beta, so it's not like I'm not playing it right now.
And I never miss a Paradox grand strategy game, so I'll be sure to pick up Europa Universalis IV when that drops on the 13th. I suggest anyone who just got into the genre with Crusader Kings II do the same. *nod*
EDIT: How could I forget Divekick?
