Should I just wait??

From my way of seeing it, I'd rather have it now. If the MMM does come out on time, odds are that it will be very reasonably priced and you'll already have a Neu motor to run with it.

I don't have a Quark/Neu combo. I wish I did, but considering all of the rave reviews and comments made about this combo, I don't think that anyone could say that they regretted getting it, regardless of the price of the MMM combo a few months from now.
