Anyone know what vendor will have P3 batteries first? Also, anyone know what the actual price of them are? Ive seen 120 all the way up to 150.  

They are $149. Some DJI dealers are taking pre-orders. For example:

https://www.advexure.com/store/dji-phantom-3-battery-extra
http://www.multicopterwarehouse. ... JI-Phantom3-Battery

As of this morning, the DJI store has the batteries, and the nifty backpack for sale.  Both are $149.

Unfortunately, it seems to say they won't ship for a couple weeks after cleared payment.  

Still don't have any of the "officially approved" Phantom 3 propellers though.

Actually, they are up on the DJI store, but there's some linking problems, and you have to try to navigate there a few different ways.

In any case, I just put an order in for a battery, the backpack, and some of the older Phantom 2 propellers just today.

The store says they will ship 10-15 working days after payment clears.  Hmmm......  It's possible local stores and ebay may have them by then.

Okay... finally found the link to purchase the P3 battery - don't know why it's so hard to find.  Here it is...
