There won't be an M770i because the V12 is a 760i and it doesn't make sense to have 770 which is a V8.
There will most likely be an M750i or M755i and it will be an M-Performance automobile - probably with an S63 engine and a weight close to that of the current M5 (thanks to carbon fiber).
The M750i car will likely offer a 0-60 time of 3.7-3.9 seconds.
If there is an M7 it will either be a tuned up version of the M750i or it will be a V12.
