Yes, I rarely purchase PC games but I can easily see myself buying BF3 when it comes out. As well... I'm really crossing my fingers on this one... when Diablo III comes out. I haven't been following but I assume it will follow the same Blizzard model as WoW and be a pay per month.
I'm sure there are other games I will be interested in (such as the new 2012 sports game) but that's all I can forsee me purchasing for now.
Edit: also forgot to mention the Zerg expansion campaign for SC2
The only game I may buy from the confirmed release date list is Skyrim. But I'm a little hesitant 'cause I kinda got bored of Oblivion. I much prefer Morrowind to Oblivion even though that graphics were bad in comparison.
The only game I bought this year was Crysis 2.
From the unscheduled release list, I will most likely buy X: Rebirth
