Let me clear things up a little (As I see it).
DJI released the phantom V1.
This is a ready to go quad which is aimed at the RTF Air Photography market, and designed from the-out set to work with the GoPro. Better, more stable, images can be obtained if a gimbal is bought for extra cash. Although for most hobbyists the supplied kit will suffice .
It was quite obvious from an early time that there were a few improvements that could help, So DJI has incorporated these in the production line. These are then referred to as V1.1 etc (I am assuming again that V1.1.1 etc would be minor changes, and that for slightly bigger changes V1.2.1 etc would be used). So, essentially, the bigger the number the newer, And the closer to the start of that number the greater the difference. (I am guessing, but it appears to make sense to me.
The bigger jump, will be a re-modelling of the Phantom . This will include new operating frequencies, add on software telemetrics etc feed back to iPhone/iPad, etc, and a camera (yet to be seen, But appears from you tube footage, to be not quite up to spec with the GoPro, and will not ship with a gimbal). This will be the Phantom Vision. Aimed at people who want to fly great RTF quads, and take good Aerial pics. BUT not the main entry level Aerial Photography Pro. And with a slightly cheaper price tag attached to it.
This is where I ASSUME ( and this is ALL speculation) the Phantom V2 will come in.
I believe that it will be similar to a Phantom Vision, but without the camera. Allowing you to add the Zenmuse Gimbal and the GoPro camera at your discretion. Thereby giving you all the pros of the new system AND the Pros of the old, BUT (Hopefully) none of the short comings of the old.
However in order to get the better quality images (If that is what you want) you will have to shell out a little extra cash for the extra kit, which will give you better results. Which is what you need to do at the moment with the DJI Phantom V1 etc.
