If you look the path, that Nuendo took. From ancient on nuendo + NEK.
The forthcoming Nuendo 8 does not offer NEK any more. It became integrated. Also some VST were standalone and became member of a collection.
If there are not so many new inventions in one software it’s possible to bundle or integrate some different programs.
Look the trend between cubase and wavelab, which work together since WL9 I think.
At some time it would be possible to do like nuendo + NEK.
That’s my opinion as I watch the SW-market for many of years.
