I've seen the new features of the P4, and while the object avoidance is cool, I don't think its worth the $1400. The only feature that I think is worth it, is the ActiveTrack function. However this functionality doesn't appear to use the added cameras, rather seems to be software based with the main camera. I'm hoping that given this it will become available for the P3A/P3P in the near future! I won't be upgrading even if they fail to bring that feature to the P3, but that feature would make the P3 an even better arial video system! What do you guys think? Will the software feature become available?
