Biggest question on my mind though: will the USB hub in the MM-1 be (optionally) powered? I doubt its usefulness without, to be honest.. It's not like people are going to plug mice and keyboards in it, and I haven't seen external power mentioned anywhere.
The hub in the MM-1 is a powered USB 2.0 Multi-TT hub. Anything less would be a waste of resources. We wanted to make sure the onboard hub would support the kind of things DJs actually use.

The CMD LC-1 is gunna play nicely with linux + bitwig, right? The Launchpad sure as hell doesn't so there may be a gap in the market there ;P
The CMD controllers are all class compliant as far as MIDI goes. Of course, the built in audio on the CMD Studio 4a will require an ASIO driver in Windows, but otherwise it's standard fare.

What currency are those prices you mention ?
Typically the prices I mention in videos are USD.
