There is lots of great code in sonar, but with so many decades if bloats and adaptations to make old and new work together, the code is likely a huge mess.
My guess is that once the dust settles a number of Cakewalk's developers will end up working for other DAW providers and some of that "great code" will be rewritten and be better than ever in a new home.
And if Microsoft think that the Sonar code would be a good base for their own DAW employing the developers will probably get them a better product than buying the source code even if it does take a bit longer.
I have serious doubts that Microsoft would ever consider using Sonar as a base for their own DAW. First of all, the MS job ads that someone posted on KVR, which started the whole rumor that they were planning their own DAW, talked about "the future of music creation in multiple dimensions." This suggests to me that they have something more modern in mind than a 30 year old app. It stands to reason, because the market is already saturated with DAW's that follow the same basic paradigm. To be honest I can't see a revamped Sonar regaining much of that market share. It would have to be something vastly different.
I have a sneaking suspicion that what Microsoft has in mind is some kind of "fun" way to make music that's accessible to everyone - the sort of thing that they would include in Windows as part of its multimedia toolbox. Kind of like their new 3D design tools - great fun and easy to use, but you're not going to find many 3D design pros using them.
