I'd wager that a non-insignificant % of the people scrambling to order want to get their hands on one to flip it on eBay. Watch what happens when they start shipping.
And if someone needs one this week instead of waiting 2-3 weeks, then they're free to spend $300. Otherwise the seller is just playing to buyer's stupidity. Oh well.
I think it's going to be longer than 2-3 weeks to get one.
Regardless, I don't see what the urgency is. If there's something you need to develop on an embedded ARM SoC, there are plenty of other more available (and less publicized) options.
