I didn't watch it live but did watch it afterwards, just google Elder Scrolls twitch.
Gameplay looks interesting, basically standard ES style but with other people. Definitely not a traditional looking MMO. May be worth a pick up, but I wish they could have just spent the resources to make another ES single player game.
ESO is being developed by ZeniMax Online Studios, created just to make ESO and so that Bethesda Game Studios can continue developing the single player game (dlc and/or a new game).
