Bafang G341 / M325 (BBS02 Successor?)

Did anybody already have the oppurtunity to get his hands on the new Bafang G341 which is probably supposed to be the successor of the G340 (better known as BBS02).
I am curious if there are any changes inside.

No details on the internals yet, but it appears that the next generation of Bafang mid-drives will only work with Bafang battery packs. I hope that is not true...

This would not be a problem because I would not use the internal Bafang controller, but use a little ASI controller instead. I am only interested in the motor.
