I think this is great news! A new lease of life. 
 
I think also there is a lot of synergy. Bandlab occupies a segment that I would suggest is 'quick and dirty' or 'collaborate on the move' recording. 
 
SONAR is a pro level solution so there could be a migration path from BandLab to SONAR.
 
Just my opinion. Let's see. 
 
 

Not worried here Thanks Bandlab! Team Green on-board.

Let's wait and see. It may take an awful long time before you see the new face of Bandlab/cakewalk. Even the name is up in the air. I can wait, until then I will continue to work in studio One 3

The green economy is what killed all the hamsters in France!

Definitely not going to lose sleep over the purchase actually I feel pretty good about it. At least there is a glimmer of hope in Cakewalks future where there was real uncertainty a few weeks ago but as you say time will tell.

Hamsters are what power my desktop work station.

Many thoughts and feelings are being expressed. Some hopeful, some cynical. All to be expected. I myself was not convinced Sonar would ever live again, and was prepared to use 8.5 Studio on Windows 7 the rest of my life (one of the advantages of being in your sixties is that you can say things like that with a realistic chance of them being true). If this had not happened, there's a good chance nothing would have. No, we don't really know Band Lab's intentions. Yes, it appears to be a company geared to a younger crowd than many of us. But technology is changing so rapidly. Will DAWS themselves even be around in 15 years, other than as ancient software used by a generation on their way out the door? At least Sonar has a chance at life now. Surely that is better than an unmarked grave in Silicon Valley.

Well Said.

There's hope!!!  Now I don't have to get rid of my Cakewalk Sonar tattoo!!!
