What about BMW Alpina from 2025/26?

Has any of you heard rumors about what BMW plans to do with the Alpina brand from 2025/26, which will then be theirs? According to my dealer, BMW has not yet communicated anything about this. He suspects that BMW will install the M-drives in a slightly more elegant car series with a more subtle look. That was just a guess, but a suggestive one, as I think. What do you know or think? For which series will BMW use the Alpina brand? As before from the 3 Series upwards or rather analog to Mercedes-Maybach? Or at the end even as with Audi-Horch only as a variant of equipment for China only?
