With 5 days left in March, I don't think that this will be available in March stateside. Sometime in april is a good guess, the availability may be limited. I am still uncertain as to what the final US state price will be.
For me personally around 150 for the xt version would be acceptable and a good value, anything above that and it would place the purchase under scrutiny by the auburn haired auditor (the g/f).

@shoggy: Is there a remote possibility that you will release a bluetooth version of the remote control?
