My thought is they will go for airgapped transactions. Personally I have a trezor model one and even though I think it's safe, I don't like the fact that I have to plug in a usb cable. Also, it may be bitcoin only (not as a separate option which is also available for models One and T)
The name is gonna be Trezor Z
Seems like Gen-Z or strawberry generation when hearing that name. In my guess, they just changed the body design into metal and not in its entirety changed the software. The feature you mentioned (air-gapped transactions and bitcoin-only firmware) is already had on all trezor (model one and T)
When I look image vaguely, that looks vape to me.
