Some internal document sent somewhere at some point today was captured by someone and then sent on to Droid-Life, and the news it contains isn't going to be making anyone particularly happy:
Here's the deal: the Thunderbolt won't be launching on the 14th (next week). Amazon and Best Buy apparently had it wrong, and Amazon has since updated its page to reflect that unknown launch date.
The Thunderbolt's Mobile Hotspot feature has also been pushed back, but I would assume this is merely to accommodate the device's new release date. The XOOM also got a mention - something about a delay with the "creative" for the device, I presume this is in reference to advertisements and kiosks and such (correct me if I'm wrong on this, commenters).
When will the Thunderbolt be launching? Droid-Life is speculating the 24th, a date that had been discussed as a possibility some time back. Presumably Verizon will continue doing a bang-up job keeping its retail partners informed and another, revised release date will be leaked soon enough.
