Z/28=NOUN
HPE, Supercharged XX, Whatever = ADJECTIVE.
Don't you agree CASE CLOSED?
Now, if they come up with a new NOUN to take the place of Z/28 like ZR1 took the title away from Z06, well then, I would not mind. Just don't give it some name that is an ADJECTIVE.
I'd buy it regardless. Just don't make it "Special Edition" HPE or otherwise.
