For me the '+' options are just different and not improvements. I would be pretty reluctant to get an mp-10 '+' but I guess we need to see it. Imo I don't see how it would be better, but that's just me as I don't think slavish devotion to the cartoon model is always a good thing.

If it was completely new...eh still dunno. Still love my MP-10 heaps! There are a couple of minor nitpicks but it is still good!
