DJI has made no bones about worshipping Apple's business model. And even Apple releases an, "S" model after every new phone. DJI is first and foremost a business. If you think they will just make a P4 and no, "S" version of it then you are deluded. They may not have 4 versions, but they will at *least* have one update to it - they simply have to.
Even if DJI looked you right in the face and said, "I cannot tell a lie. The P4 is the only version we'll make" then they are just simply lying. It's business. Look at how methodically they adjusted the prices of the 10 year anniversary saw. It was shrewd to say the least. They want you to feel comfortable buying now. And when the, "S" model comes out, believe me, all the current P4 owners will have threads discussing why the upgrade, "Just isn't worth it". There are a million ways to already improve the P4 and they will...quickly...because so will their competition.
