"Make Biab into RealBand then get rid of RealBand ?"

Band-in-a-Box may gain a more DAW like interface in some windows. I can see the audio mixer becoming a console view and the functionality of the Tracks View expanded. Because we're discussing graphic interface changes and not functionality changes I wouldn't expect to see much difference in the Piano Roll, Notation or Chord Sheet windows other than look pretty stuff.

Because RealBand has some functions that differ from Band-in-a-Box my expectation is RealBand will stick around. You may have noticed though that some effort has been made to make 2025 RealBand more pretty.
