I think it may get a CF roof - the E90 M3 came out a year behind the E92 and the cost of re tooling for the sedan shape was considered too great, with this car looking like entering production first and being engineered this far out and with BMW recent developments in CFRP i think there is every possibility of it having a CF roof/parts.
