I am sure the 15th is the current "target" date.
There is obviously a problem with the phone and Verizon does not feel it is ready to be sold until an update comes from Google/Samsung. As of right now there is no update and the phone's release date is going to continue to be pushed back until that update is ready. I have zero faith we will see the phone on Thursday unless we start hearing chatter about a software update being ready.
If people believe anything a store employee is telling them, I have a bridge to sell you.
Cheetara isn't a store employee, and she doesn't get her information from the local Verizon store. She's in the loop, somehow, she doesn't reveal her sources, but her information has ALWAYS been accurate. She confirmed this morning that the 15th has been officially approved by corporate and is more than just an attempted target date, it's the new December 9th. So obviously Verizon has solved the issue that caused the delay. It is it a software update (which is HIGHLY unlikely) then it probably won't be pushed to most phone until launch day, just like 4.1 isn't being pushed to those who got their phones early.
