Like I said it's possible since the expansion revolves around the Hutts and Varl was intended for 1.4. If you look at 1.3 in that link, you'll see a lot of it was split up and made into 1.3 to 1.6. That's why I'm certain Varl could be considered to be included with the expansion, but this is only based on presumption.
Now here is someone that reads all the interviews and remembers them.
Remember folks they said on the expansion page MORE INFO TO COME.. BUT don't build up your hopes and dreams either. It's a game if it happen it happen if not GO THE FREAK OUTSIDE!!
