The only problem I see here is that Castle is going to get left behind in the 1/8th scale area. The MMM is great ESC and the Castle service is second to none but have a look around and you will see that everybody is pushing into the sensored 1/8th ESC market. Hobbywing, Tekin, MGM and Novak have 1/8th Sensored ESC (although Novak being only 4S capable doesn't pose a huge threat) and even Toro8/Trackstar 150 will be available in sensored version really soon.

What I think they should do is keep the current MMM as there is nothing really wrong with it but sell it along side a MMM Pro (or what ever they want to call it) which would have: Sensored operation, solder posts, data logging and Bluetooth or Android application capability. Being Castle and the ESC being backed by theirs second to none service people would be willing to pay a fair bit more than for the standard MMM. Heck, I would for sure.

I think it would be worth it but then again I am not a business man and it's not me laying out the money on the development. I just Hope that Patrick's limited input and total silence from the other Castle techs means that they are working on something like whats being discussed in this thread and just want to keep quiet and give nothing away. Well I hope so.
