Just as unlikely for either of the two. Dude, cmon, just try to get it, there is no contract with the BMW itself providing the cars. It's just a coincidence that we have 2 beemers (formulas) in. It's just as likely we get a new BMW as is likely, to get another finnish car in. Unless the devs score a real BMW contract.
The whole 6, either the normal 6, M6 or X6 has been a total psychedelic trip for BMW as they haven't produced a single, at least somewhat normal looking vehicle. THe new 6 series drawings do look nice though, it takes a lot from the CS coupe.
But idk about everything crammed into one.. Maybe on the beta versions but already we dont have enough track content.. You'd probably see a test arena and get bored of it too quickly.
I dream of holding this thing on opposite lock through 4th gear corners, watching the 4 little front wheels flickering in unison with my steering commands...
That reminds me - Tracks need more bumps/imperfections (I think the current track surfaces are too good), and I'd like the cars to exhibit more steering kickback.
