Just pre ordered the Mavic Pro Fly More Combo. While I have been VERY happy with my P3 Pro and only slightly lusted after the P4 for the advancements it includes, I have ALWAYS wished it weren't such a hassle to carry around my big bulky and somewhat hefty Nanuk wheeled case. I agree with one of the other users who said his take (I think it was KingKong) was that it appeals to hikers and backpackers, etc. I agree completely, but I also think that, at least for me, I will be MUCH more likely to charge up and take the Mavik in the little bag along to many more places--especially when I go out on the boat. It's really a matter of convenience. I think the Phantom will continue to serve a more narrowed niche, especially for people who use their Phanton for business (Realtor here) because it seems (though I could be mistaken) that the P3/P4s and beyond will be a tad more stable. Just my 50 cents. I hope I got in early enough on DJI's Site that I'll get one of the first releases. I tried for hours and just couldn't get it to continue the checkout process.
