The current gen version actually came out yesterday, I've bought it already despite having it for 360 and PC (XB1 version, mainly for the missus)
Skyrim was an odd choice for show anyway if you ask me - why take [the HD version of] a 5 year old game, that frankly plays very similar to the new Zelda game you've just piggin' shown a few seconds earlier, as if it means as much to your fans as that game does?? I'm a massive Elder Scrolls fan, but having an old-ish entry almost overshadow your flagship Zelda was round the bend if you ask me.....
Suppose it's big news if only to show that Bethesda are on board - perhaps Fallout 4 would've been a better choice title though..?
