Considering Bruno and Alex have been at the pointy end with basically kit standard cars with very few (and then only subtle) prototype parts *and* money no object (almost) infinity drivers such as Jilles are running T4's by choice suggests it definitely won't be a revolution.
Definitely think we will see Carpet and Asphalt editions - the XB2 has set that trend for them now and sold well.
Would be nice if the asphalt one comes with a graphite chassis that is backward compatible and includes graphite plastics cause a) my graphite chassis is quite worn and b) I don't need another set of std plastics I won't use
