My guess is Alpha would be 25 million or higher if they bring the Hi-4T variant. It is larger than a Revo, significantly more powerful with much more tech so it's not going to be cheap to manufacture locally.
For context, the current CBU Tank 500 is the exact same platform at 45 million without the Hi-4T system.
That said, BYD is definitely going to introduce the Shark before that and Canon Alpha is a much better truck than the Shark so you can expect it to be priced higher than it.
