What do you need, a giant sign lit up in neon stating formally it's dead with Ben Herman's signature on it, supplemented by a mass mailing of condolence letters? It's as much as been announced that it's dead, if it even ever actually existed in the first place.
Did you see a formal announcement from Hyperion about the other Mystery Devices from the mid 00s being canceled? I suppose you're still waiting on those as well...
As far as ACube goes you should probably get that SAM. ACube has proven to be a reliable company and has supported their users fairly over the years, I'd trust them long before trusting Hyperion.
