It will eventually reach the stage I think when people will decide to upgrade less often, in other words they will have so many realtracks that they will decide enough is enough for the kind of music they produce.
Maybe then PG will turn its attention to the midi styles 90% I feel that are so outdated that its a pain to listen to them.
Don't get me wrong I really love band in a box my favourite music programe and realtracks are the current flavour of the month but this won't last I think.
just my views.
