Not quite dead yet, but dying.I finally upgraded to a P4 from a P2V+ and the difference/progress is amazing. I enjoyed my P2 but the 4 is so much better. Yes the support for the P2 apps will stagnate or die. On the plus side the spares and batteries etc are now excellent value, and they are so easy to open up and modify.
Before I upgraded I became much more adventurous with the P2, thinking well not too much to lose now, but it always came back safe and sound. I am much more confident with the 4, there is much more redundancy and protection, but still got fond memories of the P2.
If I had kept it, I doubt I would ever have flown it again.
