Iscorama hanging on the Pocket. It's like when your girlfriend teases you in a sexy lingerie..
Besides I only have a few observations about this one:
Well, I think the "Pocket" concept is great because if you want to you can keep it really simple but seemingly it also let's you to buy cheaper rigs. Even the best looking Movcam/Tilta cages cost like 50% less than the older BMCC ones. Sure, you might end up spending more on memory cards (I believe this could change soon with more SD manufacturers in the game) but move on to the other things:
User replaceable batteries. The other Cinema Camera has one built in, but personally I like the option to change it any time because you are not restricted to plug it in a wall socket or an external battery. Probably I will use an Anker Power Bank anyway, but it's great to have replacement Nikon batteries in your bag just in case.
Also there's this topic on DVXUser where someone measured the BMPCC's rolling shutter rate, and actually it performs better than the BMCC - 17.8ms vs 25ms - not bad. I hate rolling shutter and the less I have to see it the better it is.
And for last, it became clear in the last few months that the Pocket's firmware gets updated more often. Blackmagic (obviously) places more effort into supporting it's new line-up which really puts the older camera on the legacy shelf. I feel more secured by getting the new camera.
