I'll probably wait til next fall when they have a big price reduction before Vue 11 come out. I can see maybe waiting a couple of versions, but 5+ is too much. You'll lose out on the upgrade pricing and probably have to pay full price.

But speaking of pricing, I got an email from Eon about the printed manual for Vue 9 being on sale half off and I was ready to buy until I realized that they charge $13 for shipping! That's half the cost of the book! I cancelled the order when I saw that.
