I don't think they would. There are a LOT of other RC'ers out there who aren't brushless-brains, and who just want a powerful system to drop into their E-Maxx, for example. An ESC on it's own isn't going to be hugely attractive to them, as they still won't really know what motor to choose...and it's tricky. A combo, complete with motor, will be the perfect ticket for a LOT of people. Sure, many of us here would like the ESC on its own, but there's a whole other market for those who just want a complete system to drop in.
There aren't really an "ideal" big motors out there for the less knowledgeable guys; Feigaos are inefficient and fall apart, and Neus are nice but very expensive. The CC motor should be just the ticket.
