I can't see how they abandonded the indie market.
This beast is still SUPER cheap. And if you need something cheaper you still have the previous models (from BMCC to URSA Mini 1 and the Pocket and Micro).
I own a Pocket and I love it (even if the LCD and battery are crap), but I can't understand the hate for the Micro. For me it's clearly the way to go. And I believe they think the same way, as clearly the URSA Mini is the way to go for them (the Major is pretty dead).
It seems they learned fro their mistakes and that's why they didn't announce new cameras at NAB last year. Announce things if you can actually ship them, that's the way to go.
If they announced this now, instead of saving it for NAB and steal the show it's because they have something else in mind. Clearly, It can't be URSA or big model related, so meybe a new Micro model with new 4K sensor, extra modules...
