Labatory Bakers have something prepared for us.

The first version will almost certainly be a rebranded SONAR, with maybe a few goodies added, but I wouldn't expect anything beyond that at first.
 
Later on, who knows?
 
The possibilities are limitless.

Didn't we already have this thread?

Flagship means top of the range version. It doesn't mean an amazing new version. Sonar Platinum was Cakewalk's flagship DAW. In this timeframe, I anticipate it will be rebranded, have the LANDR integration replaced by Bandlab's version, have the last update we never got (Oct 17?) applied and maybe some extras to keep us interested. On top of that, they might announce their plans and vision for the future, but not to the extent that it would help their competitors. I wouldn't be surprised if they keep the monthly updates model as that seemed to be working well, was popular with users and popular with developers. But I don't think anyone should build their hopes too high for the first Bandlab Sonar release or you may end up being disappointed if you expect too much at this stage.

I am hoping for, though not necessarily expecting, the October / November Update - whatever was in the queue for release, finished and ready. I'm also hoping for the announcements of a Roadmap for where the new DAW is heading - things like will there finally be an update to Notation/Score Editing. Beyond that, I'm curious how much SONAR will be in the new product (what things have to be left out, beyond LANDR - other Third Party stuff that BandLab either can't or has decided not to keep, for example).

I can't remember where I read it now, but the guy from Sonic Scores who develops Overture 5 said that he had been working on a deal with Cakewalk to integrate Overture features into Sonar to replace the crappy score editor. They came up with a great deal but when Cakewalk went to Gibson for the go-ahead, Gibson trashed the idea. They came back with an even better deal but Gibson trashed that too. I don't think this was long before the closedown. Perhaps that could become a reality now that Gibson is out of the picture.
