Actually...I just realised how many games are coming out next year. Uh oh. Anyway, the big one for me is The Witcher 3. I'm a massive fan of the series, and the books. I'm even thinking of giving the TV show a go... That said, there's plenty more games I have on my wishlist for next year. It feels weird talking about a new large scale RPG now that I'm still playing Dragon Age: Inquisition.
Also really looking forward to Zelda U, naturally. Hopefully things look up for that though, I'm not sure how much I'm liking what I'm seeing of the gameplay. However it's early Alpha so we'll see. GTA V for PC is a big one also. I skipped over GTA V spoilers completely for the last year and will be coming into the experience with fresh eyes, which is something I can't wait for. Plus, mod support. Arkham Knight is something I'm looking forward to, even though I do feel that much of the Arkham games are sameish. They're consistently enjoyable, but I don't find much replay value in them personally. So in the same skeptic view, I'm awaiting Tom Clancy's The Division. Ubisoft have had a terrible this year, their most successful title being South Park: The Stick of Truth. So who knows how good The Division will be in the end.
Lastly, I'm looking forward to Rise of the Tomb Raider. However I'm not sure if it's been officially announced on other platforms for 2015 due to the timelock that Microsoft have so acutely bought for it.
