I totally agree about the VA7/76 being well below what was expected. I have owned both of the instruments (not at the same time) and sold them a while ago, keeping my G1000 and SD1. The VA range is just a glorified G1000 and far slower to use in a live situation. The sounds and styles don't make you go wow like they do with the SD1.
The real competition will now be Genesys, Tyros, KN7000 and Solton stuff
