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.
