I had pre-ordered these on Amazon back in November and had gotten an email notification earlier this month that they would be shipping by the end of the month... well, now it's the end of the month and I just got an email from Amazon asking me to confirm if I still want them because the order date has changed to "TBD"...
New estimated delivery date: Not yet available. We'll e-mail you as soon as we have a delivery date.
Super frustrating - I wish we could get an official word on this. I'm not impressed by what's out on the market and hope these are worth the wait!
