I registered 2006.  But, because I don't qualify for the free 2007 upgrade(by 10 days).  I can get the upgrade for $10.   I'll pass.  I don't seem like it's much of a difference, anyway.  They added props and a gold suit.  I've never seen a Santa in a Gold suit.    It's also includes the 2006 version.  2007 is cheaper than the version I have.  If I didn't have 2006.  2007 would have to include 2006, for me to make the purchase.  

I'll do fine with 2006.  The upgrade does not offer enough to make me shell out the extra $10.
