I thought they might. I don't tend to use many plugins and I don't use much more than the included or "Stock Plugins" including Fat Channel. However I did notice that when I installed v5 in the summer the upgrade process on Windows was an absolute breeze. I didn't have to mess with anything at all. I didn't even tell v5 where my VST'S were, they appeared where they should be. To quote a famous videogame developer "It just works" ;)
