What are the fundamental differences ?

I intend buying a VA7 this year and I want to know how do I tell whether the dealer is selling me the latest VA7 or an older one....These keyboards dont sell well here..which is why I'm afraid of blowing my money on a VA7 thats old (even if its still sealed in the box).

I read somewhere that the new VA7's have the wizard music set up feature ? When did this come out ?

Also, If I go for the VA76, will that defintely have all the latest updates included (since it came out recently).

Hope someone out there can answer.....
