The fan and extra surface area of the MMM are what make it handle much more continuous current out of the box, but since the MMpro will have fan that is removeable, you are set for at least any 6s 1/8 scale racing setup.

Well - not quite . It isn't just the number of FETs, but also the design (cooling is very important). The MMM has a large footprint (as you mentioned) and has ALL its FETs on one board cooled by a large heatsink. The MM has SOME of its FETs attached to a smaller heatsink. The rest of the FETs are cooled indirectly through the copper on the board attached to the "cooled" FETs which are attached to the heatsink. I think the MM has less FETs overall vs. the MMM as well(been a while since I have had one apart). less FETs and less cooling = significantly less power handling capability.
My MMM almost never comes in with its fan on(only comes on when i plug it in) - even on a hot day. Without a fan in the same scenario, the MM would thermal(and would thermal with a fan occasionaly as well). If the MMPro has the same basic layout as the MM, I would expect similar performance. I think the MMM pro may be a good 1/8 buggy esc on 5s perhaps, but I also think it will need a milder setup to survive vs. the MMM.
