Historically it was Microsoft with their lower price and rather bro-ish/family crowd, they have a good crop of exclusives this year and the Halo bundle should tempt long time fans into a purchase.
Nintendo have the best exclusive games so far this gen and a cheap price point, so far this hasn't produced strong sales but with Mario Kart and super smash bros brawl as long standing system sellers they should have their best year so far.
And Sony the current sales leader, with exclusives proped up by the family friendly Little Big Planet 3 and stong ties to big games at the end of the year like Destiny and battlefield can they increase the pace the most? The last of us for anyone who missed it last gen can't hurt.
Buying order: Switch, better pc
