It is the Q3 (if it exist anymore), or a good extra update and the Q3 will arrive "soon"? @Coutie
I think they've been pretty clear about this Q3 lacking new content and getting this update instead. But there's something new coming, Probably the new CS.
After this update everything seems ready for it. BTCC, GT3 and GTE with new BOPs, FISI updated, older open-wheeler updated, some older and popular tracks updated...
