The documentation I've been able to find leads me to believe that is the only difference. From a financial perspective, there certainly doesn't seem to be any cost advantage in maintaining two different SKU's (a stand-alone CTRLr and a different model packaged with MOJO). In fact, the opposite would logically be the case.
I imagine the bt combo chip would cost more then just bt4, in hardware maybe in licensing also...
BT2 is slow and less energy efficient so that's why it's not required on mojo.
But you could be right, it's only the first few batches, so I'm sure there's still some tweeks that could be made in production.
I was hoping they lowered the Dpad (PS style) and raised the mode switch from a grove to a grip tab thing.. oh well.
The price dropped from $79.99 to $59.99 which is a great price I think for the features and very competative.
Speaking of sku's, I wonder why they have the CTRLi and not added iOS support to the retail CTRLR, it would have made the CTRLR even more impressive:highfive:
