Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Does anyone really think Holden is going to sell Corvettes? https://www.holden.com.au/cars/corvette
Reportedly they won't be here till 2021 so given that it is unlikely Holden will exist in 2021 the answer to your question is a resounding No.
Then it will have been a real commodore even with no V8. For me Holden lost me by shutting down Holden in AustraliaIt is funny reading about everyone saying the ZB is not a Commodore but if Holden continued manufacturing in AU, the ZB would of been the car built in Adelaide.
