All 3 companies had a freaking awesome 2013, imo.
Sony had a stellar PS3 line-up, a decent PS4 launch line-up and a good Vita line-up. Conference-wise, in between PS Meeting, E3, Gamescom and TGS, Sony had a good show at each event, with multiple announcements at each show. (E3 itself wasn't all that good content-wise, but noDRM and $399 was a showstopper never to be repeated again)
MS had a poor 360 line-up and a great XB1 launch. Conference-wise, E3 was freaking great, but they pretty much had a weak show at Gamescom and TGS subsequently.
Nintendo had a lacklustre WiiU line-up, but the 3DS was beastmode. Conference-wise, they've got nice games announced for 2014, but they lack the excitement and hype of other competitors because while great games, it's what is expected.
