I had two bundles going circa 2002. I decided that WUP was a dumb move so I Waved goodbye. I guess if you update all your operating system and other software every year, then maybe? but I keep a system going for about ten years typically - kind of like a car.
Like if Ford had a WUP requirement. Really? the Waves WUP is sort of like "leasing" the software., so you can get an updated car every year or so. Makes no sense to me.
there are just too many great plugins that compete with Waves now for this to make sense.
I do like my RenComp and the Vox thing, and the Mushroom Pusher.
Put the $300 Wup into buying some other cool stuff.
