Probably alpha since not all the cars are converted. As far as I know (I'm not doing the converting) most, if not all of
these 2012 Blancpain cars will be included. PetraGTC has permission to do the lot of them- so that would leave the Audi R8 LMS Ultra (not sure abut the non-Ultra R8), Ferrari 458 Italia (this one may come out this week- not sure), and Lamborghini LP600+
Included already are the F430 skins for the Race for 3dSimEd3 Donators- and they are stunning (obviously MINE is the best!)
After the conversions are done, there will be work on shaders (graphics) and physics tweaking and performance balancing. Right now the Merc is just too fast and blows allt he other cars away. The F430 is the slowest (but that's by design- it was an older model in the series and did not contest all the rounds).
