Depends, it always takes ages for Audi to get the RS model out...
This 'was' the case and I was just about to say the same thing tbh. However, the new versions of the RS4, RS6, RS7 etc are no where near as long on their release as the previous models..
Either way, you won't be sat in a new RS3 for a couple of years at least (if they do actually release one that is)!
