i believe that "Bounce in place and themes" belong to a 8 version update, especially themes seems too much of a marketing trick to be 9 only,
as for free updates thats a whole different strategy that only proppellerhead can justify and i dont see it happening soon
(but it will be good if you have a discount only if you upgrade from the last previous version and full price for all other versions, then more people would upgrade to the last version faster but if the current system works pretty good financial then why change it, also the way it is now is a tradition thing after all these versions
