whether its protocol compatible or not, the construction likelihood is that a Supercharger to Chaedemo adapter will be cheaper than a Supercharger to CCS adapter, and that a Supercharger to CCS adapter may actually be a Supercharger to Chademo to CCS design.

[There are some who have se listed on the TMC forum, that many of te Chademo chargers will be getting the new SAE J-1772 DC Frankenplug added to them. If that becomes a reality, Tesla will just produce a J-1772 adapter with the Frankenplug, which is electrically compatible to the Tesla protocol/standard. Those adapters will be a lot less expensive, since the will just be physical connector adapters, and not likely to have much, if any electronics in them.]
This is not correct. The "Frankenplug" is not upward compatible with J1772, only backward compatible. This means that while the Tesla can accept standard L1/L2 J1772, it will not be able to use the Combo without adding a lot more stuff, including the power-line communications system used in the Combo system.
Actually, I posit that a CHAdeMO to supercharger adapter is easier and simpler than a SAE Combo to supercharger!

All the Tesla hacking
Supercharger protocol for diy CHAdeMO adapter seem to validate Ingineer's posit, that CHAdeMO to supercharger adapter is easier and simpler than a SAE Combo to supercharger
