Fun discussion, and I've been in this place before, myself. So, here's my take. V-Vocal probably is End Of Life because of
x-reason. Some products are useful far beyond the end of their lives, so we can continue to use them until something better comes along. However, I have two suggestions:
1) In my sessions, if I need pitch correction, it's likely because I didn't catch the bad notes or bad pitch, but my needs are routinely minimal. Melodyne works pretty well in those cases for me.
2) Another suggestion is to inform Melodyne what you sincerely believe V-Vocal does better. I'm sure if they know V-Vocal is going away, they'd do what they could to improve their own product with less worry of patent infringement (especially if CW owns/owned V-Vocal).
