If it makes you feel any better mine hasn't been shipped either, in spite of being a fairly high-tier backer. Even being a forum mod doesn't get me priority treatment.
Larian are pretty good guys, not sure why the shipping schedules are a bit tight, it may even be a stipulation by the likes of Valve that they can't be sent until the day before the release date, though that's pure conjecture. Patience is a virtue, they say, though I admit that in that case I'm not very virtuous.
