I guess it's all still in transit through the primary distributors (online distributors are mostly secondary - they don't get it directly from publishers).
I had an email from a fan today:
"My cousin and I got it! US Games sent it direct and IS IT BEAUTIFUL! You should have seen us jumping up and down and squealing - hey, it looked like Christmas morning! Congratulations Kat, they are beautiful beyond description. Well Done! Thanks - Krislyn"
So hopefully that's evidence that it really is on it's way to all the other distributors! And also (HUGE sigh of relief) that it's not a disappointment in the flesh
You guys have been waiting six months and suddenly you get impatient?

Give it another week or so and the distribution should be all sorted out.
