I'm sure he wasn't referring to unreleased cameras...
I'd like to think that BMD's silence means all is going according to plan.
It's not that uncommon to only see images once the cameras are out, they might be optimizing it till the very last day.
Most people see the 4k camera as a whole new product that will be a cumbersome task for they to overcome, but it's basically the BMCC with a different sensor, should be no big deal really.
Also, I learned that pre orders are for fools. From all the few things I've preordered lately, I got none before they were easily available everywhere else, what's the point? (on top of being a greater risk since you don't get to read all the reviews beforehand)
