Stumbled upon this interview of Ryan with the new ShopBot Zeta by George Vondriska on YT:

Looks like some major mods of the PRS Alpha. Impressive multi-bit drilling head, lower rails for side loading, new style ATC.
Surprised no word here nor website yet.
Turns out, they have been working on something fresh to stay competitive in the full-size machine category.
I'm very intrigued and await more details...
Go ShopBot!
