My 2 cents; I own and use several Waves plugins(I tried to drop them back when the AAX conversion happened, but ultimately couldn't get what I wanted without them). Back to the present; having bought over a long time period, my WUP dates are all over the map(err.....calendar?), but as all are still working(I have a mix of 10, 11 and 12), I am waiting for the most recent to reach the WUP date so I can update everything in a single purchase(but I do plan on updating when that time arrives)
