The main factor here - from the outside looking in, to me - is Craig Anderton. If anything bodes really well for Sonar not being left to wither on the vine is him being there.
I think Craig being involved maybe directly neutralizes a lot of the potential fears. Now if they put out a press release a year from now saying Craig is leaving Gibson, yes, that might mean trouble is in the air for Sonar. As long as Craig is there I wouldn't worry about the product.
He indeed may be Sonar's biggest fan.
