I've played the opening hours of the game, clearing the tutorial area and reaching the point where the class-based mechanics start opening up to the player. I dig the pairing of Robert Boyd's design approach with the writing style of Jerry Holkins and, thus far, it feels like a proper extension of the series despite being dramatically different from the two prior titles from Hothead Games.
The game hasn't cropped up on Xbox Live Indie Games yet, having experienced a short delay while a rather unlikely bug gets ironed out. Not being able to set a firm release date for your game is all a part of the XBLIG experience, though, so I'm sure we'll see it there toot sweet. Or you could just pick up this version and skip the wait.
