Either way, in an interview with the M boss awhile back. He said he wrote off the LSD for the M235i to make it available. Whether it's an option or not, is not known. I'm thinking it will be available from the M Performance line like it is on the 4 series.
the M135i has the same e-diff as the E82 135. No LSD available. Perhaps they will offer it as a port-installed accessory OR people will just have to delve into the aftermarket as they have in the past.
EDIT: oh this is the interview you must be referring to:
