Afaik, Blizzard never once released a dodgy beta (not to mention, Blizzard beta its one of the most properly made beta for a game out there), and imo their beta very close to final product.

Thats why Blizzard takes much longer to release (as u know beta was delayed) beta.

I guess its always an advantage having the game fully developed and published themselves (as they don't need outside influence like external publisher that normally push them to release early and ignoring major bugs etc. to get fast profit).

And yea, can't wait to get this game.

Cheers
