I know I'm not the only one keeping my Steam up in hopes for the new update!
As for release it's not concerning at all to me, but I've been around for a long time. They've been very forthcoming with patches, there's a ton of unique mechanics and yet the game engine runs very well and bugs are for the most part minor for being just out of alpha. Quest bugs will happen but are the types of issues that can be quickly remedied, especially given the nature of the creation toolset which, I'd assume, will allow editing of pretty much anything in the game.
Regardless, Larian knows they have something special with this game and I believe they have all the intention to do it right in as many ways as possible - including the release state.
