The lack of Metroid in that list is killing me... :(

Not getting the XBox One until later in the gen... If I get one.

So far I am certain t get:
Forza 5
Battlefield 4
Halo 5
couple of kinect games (not sure which one yet, but would love to see how much it has improved - so maybe their sport game and an exercise one).
Mirror's edge!

Maybes:
Quantum Break
ryse

Me Personally only inFamous Second Sons and the Oddworld remake interest me. Oddworld was the game the surprised and excited me the most; I love Abe and I hope they do Exoddus remake too.

I thought Knack might be an acceptable substitute for Ratchet and Clank, but I'll wait and see on that.

Will also be getting KZ:S for my son, but I doubt I'll play it.

Not sure on anything else at this stage.
