So I actually just got off the phone with my friend at NAB who I had ask a ton of questions over at the blackmagic booth. Here's some information for those that need help.
1.BMPC sensor sensitiy? Rep said 400ASA.
2. DR? Rep said 12 stops. (although EOSHD says it's probably the same as the Leica M sensor which is closer to 11 stops and change). My friend mentioned that the rep made it very clear that there will be a noticeable difference in the look as far as sensitivity and dynamic range (similar thing that Browley said in his blog where he didn't sound so confident).
3. Why production camera? Rep mentioned that the production is just that- an answer to productions with a movement more towards TV and Broadcast as opposed to the BMCC. Thus the 4K, 6G SGI, and Global shutter.
4. Is the BMCC tailored more for cinema than the BMPC? Rep says yes.
5. How good is the global shutter? I had my friend shake both cameras to test the difference and my friend said the BMPC has a noticeable difference (meaning much better-as expected) but that the the rolling shutter in the BMCC is not horrible. I've used the EF BMCC in the past and it's ok as far as rolling shutter.
6.What does "visually" lossless mean? Not an extremely noticeable difference, still a DNG, but with a compression of about 1.5:1-2:1 (which if I remember correctly it's what Brawley said).
7. 4:3 mode on any of the cameras? Rep says nope, up to now just 16:9.
8. What is the timeline roll for the MFT BMCC? Rep says things are moving along and should be catching up to backlog soon (did not specify if backlog means EF or MFT).
9. Any new features in the next firmware update? Rep said audio meters and then didn't really get specific or provide a timeline.
Currently I own multiple MFT glass- alot of them f0.95. That coupled with 800ASA sensitivity and 13 stops of dynamic range and 2.5k raw, I think is more than enough. Not to mention that I can use pretty much any other glass on it. It's funny that I answered my own question but I was never expecting to find out so much information from my friend at NAB. He (who is a filmmaker as well) mentioned that he would also get a MFT BMCC over the EF BMPC. I hope this information helps
