This may have been cleared up earlier, but I just had to ask.

What does the addition of the knob mean for owners of both generations? There's a couple ways I could see this going. I suppose my main question is how will the software be affected by the knob? And how will this affect MK1 owners? Will the knob be of less use in attempts to assure the backwards-compatability of the software? Or on the flip side, will the MK1 owners be left hanging or with bugs because the new software will support something that doesn't exist on their units? Or is it that because the knob will just controls existing functions, the old owners won't be affected?

I know I'm not expressing this very well, but I think you can get my basic question.
