M5 Max has still only 128GB RAM at most; one would expect 192GB if there was any indication M5 Ultra would have 768GB RAM?

It is a rumor at this time and we are going from M3 to M5 on the Ultra not the M4 to the M5

The maximum memory configuration for the M3 Max MBP was also128GB.

That's my whole point. M3 Max 128GB -> M3 Ultra 512GB. M5 Max 128GB -> M5 Ultra 512GB. But if M5 Max 192GB -> M5 Ultra 768GB, i.e. Ultra having 4x the memory of Max.
