Maybe.. but who knows what will happen in 2015. If MS keeps undercutting sony in price, not sure sony will be dominating next year.
I know what will be happening. Just look at the first half. Not a single big AAA exclusive for MS in sight (At least not that I am aware of) meanwhile Sony will have Until Dawn, Bloodborne and the Order 1886. It's not just about price you know, these are GAMING consoles. They need games.
