I agree. The C6 ZR1 probably
I agree. The C6 ZR1 probably wasn't affected much by the C7 ZR1 but as you said the C7 Z06 would have done it's damage. I would imagine the same will apply here. The C8 Z06 (or equivalent) will do the damage to the C7 ZR1, at least initially, because the base model to be announced tonight won't match it in terms of performance.
