It's really different markets. Sure
P4P can do some things almost as good a
I2, and many things way better. But the
I2 can do things P4 cannot, at all.
I2 and up are professional applications, and they cost more. Frankly,
I2 and higher are way more time consuming to transport, assembly, fly, and maintain. You really need to have a good reason for an
I2 to justify the cost.
P4P can be toted around anywhere very simply in a backpack, and delivery near professional results, a "Prosumer" drone IMO. Try taking an
I2 on vacation with you, it's a real hassle in a hard case, and when you get to where you're going you'll need a car to take you to the launch site. You can't backpack or bike with an
I2 on your back very easily. Phantoms clearly have their role and niche. I think you'll see them evolve Phantom for another several years IMO. There's plenty they can do to improve the design, it just depends on what DJI chooses to do.
