I did the upgrade-$99
I haven't found anything special. It seems that it processes faster, but I guess I don't use it for much more than a wave editor.
I've got to throw in a caution here. When you upgrade to 7.0 you loose the Wavehammer plug-in. At least when I selected it last night I got a popup window of all things, directing me to the Sony site to look up the "new and improved" wavehammer.
So, it appears Sony has the marketing program in full control.
I'm going to try and reinstall 5.0, and see if I can get wavehammer back. If not, not so bad for me, because I have the Sonitus suite in Sonar which I find VERY good.
So just a word of caution to everyone.
The $99 upgrade price was worth it for me for only one reason so far, and that is to stay up with "supported" technology. That is if there ever was support on sound forge stuff anyway.
