What I was told today (from one of the dealers) is this:
Pocket camera is shipping is low quantities (i.e. less than 100 units, I was actually told about 10 at a time). The manufacturing is apparently happening in Singapore.
The same dealer told me that the BMCC is also still a slow trickle as well. He mentioned that even right now he doesn't have any in stock and the only way to get some in is to start calling their distributor and raise some stink to get them to move quicker. In all fairness, he did say that BM is not as much to blame as their distributors who sometimes tend to play favorites (i.e. prioritize bigger dealers like B&H vs. some of the smaller dealers).
His opinion is that the BMCC's image quality is likely to outperform the new 4K camera, he also feels that the data management will be an even greater issue since 4K footage (at the Pro Res file size) is still quite huge.
FWIW, I recently ran a test on the Alexa, the BMCC and the 5D3 (video coming soon), and even though I feel that the Alexa produces an amazing image, the 5D3 raw was IMHO a much better image than what I was able to get out of the BMCC.
Either way, these are very exciting times!!!
