i called sonicblue customer service on wednesday to ask this very question. here's what i found out: the estore site is operated by digital river. they do not have a link into the sonicblue inventory system, so any updates regarding what's "in stock" or "out of stock" must be done by hand.

they've gotten a flood of orders over the past week, and the warehouse has been closed for inventory, so sonicblue can't even give an accurate determination about whether your order will be able to be filled or not. until they actually match boxes up with orders (which has begun, it sounds like), you can't be certain one way or another.

i did ask if they would contact me if they ran out of my preferred size, and give me the opportunity to change to a different model. they customer service rep didn't know for sure, but he was not encouraging on that point. i placed a second order for another size to be on the safe side, and i'm confident i can recoup my investment if i end up with more units than i really want.

good luck,
