Oh No, I hope they do not do away with V-Vocal. I have melodyne pro and V-vocal has so much more flexibility greatly due to the pencil tool. Melodyne is very ridgid with limited control. it shift & slants waves where you don't want them. It was $300 down the drain for me. KEEP VVocal
you'll still be able to use v-vocal with x3 if you have an earlier version of Sonar installed in which v-vocal was included. I'm not sure exactly in what thread I read this and who said it, but it was cake-staff, so you've got nothing to worry about :)
