I will add a poll once several replies are in, to have a better list instead of just the stuff that I can think of
Off the top of my head:
PSVR - there'll be a lot of eyes on this (as well as VR in general). For console gamers, this is the VR device that matters, I expect a lot of talk about it on gaming forums next year, and its sales will be intriguing to say the least
NX - Obvious..not much to say. This will probably win the poll, lol.
Uncharted 4 - In the midst of a lot of "franchise decline", how will this one stack up in the current market?
Gears of War 4 - same as U4.
