So I saw Rob's announcement that D&M did NOT purchase the Empeg line with Rio, so support is discontinued.
They didn't purchase the support operation, i.e. Rob Schofield only.

Is Sonicblue even going to be around anymore?
No.

What do you guys expect to do now?
Carry on working for Rio, which D&M did buy. Planet Empeg comprises Rio's entire software engineering team, and is unlikely to be disappearing en masse any time soon.
