The inside info (aka rumors) over on the EW forum is that Steinberg will be developing a new stand alone Notion product from the ground up.
I'm not familiar with the EW forum, but on other forums, the speculation is the same, although there is further speculation that a subset of the newly developed code base could end up in Cubase, which has some of its own limitiations.
This would be similar to the Sibelius funtionality which ended up in Pro Tools.
Boy, I wish Roland would buy Finale or Notion.
