I´ll never going to understand you guys...now we have almost every FIA GT3 official cars (hope the Aston´s comes too) and yet we are talking about "not having" the RM´s...
RM cars were "made by us" (I mean we bought the package upgrades in the game from a regular specific car) so it is normal to not see them in the official car list if you think about it for more than a second.
So no one knows if we are not going to get them again because as far as I remember RM´s were part of the customization.
Again, we just don´t know yet and hope to see the Aston Martin DBR9 and Zagato GT3.
We have BMW M3 GT/GT2, BMW Z4 GT3, MB SLS GT3, McLaren F1 GTR (2 versions), Audi R8 Ultra LMS, Nissan GT-R GT3 N24, Lamborghini Diablo GT/GT2...looks good to me and even better than before.
We can´t have it all...enjoy what we get and maybe then we´ll see the rest...Car list is not complete since MB cars are not there and many more...
Also always read the tiny letters:
"* This list is one part of the cars planned for inclusion, and is subject to change.
*
indicates that the car is appearing for the first time in the series."
