Personally, I'm interested in the P3 too, just not willing to prepay based on the failed support P2 owners have had to deal with (can't speak for P1). I replied to this thread because I don't believe that DJI has learned from the past, otherwise they would've already taken action to support their current customer base. Personally, I'm stuck on an older version of firmware because it works, but I'm missing out on new features. Newer versions have posed even more problems and I will not upgrade to a firmware that is posing problems for others.
Thus some of us are predicting the same long "beta testing" phase as usual and I am no longer willing to support a company that does this just because they want to start selling quickly. Also, I have never prepaid anything before. I don't understand why a company the size of DJI should receive a 0 interest loan for manufacture based on a presentation. Either make thousands and sell them, or make it a Kickstarter campaign.
