My guess would be that if the empeg guys say they want to 'revisit' the Rio Receiver Software after 2.0, then I would guess thats because the Rio Receiver is not yet EOLed and is a requirement with the HSX 109 for multi-room audio.
Without the Receiver the HSX109 is one expensive piece of kit.

Therefore I suggest that SB will be funding this development [whether SB knows that or not I can't possibly comment :-)) ]
