Indeed pricing info is still missing. For MD2 they had 3 levels of license, with the 'personal' license indeed selling at or around USD 200.-, a 'developer' license at abt USD 400.- and an 'enterprice' license at USD around 600.- In the latter two versions the animation editor plug-in (USD 100.-) was included, but otherwise functionality was the same. The choice of license had consequences for what you were allowed to do with the models. I frogot full details, but as I understood it, my personal license allows me to sell models only at the MD marketplace and make generated .obj's available as freebie, and of course otherwise I am free to use the models in my own artwork.  

I understand that as a registered MD2 user I have a 50% discount on an upgrade to MD3 until 15 July 2014. Consequently, I think there will be no or far less introductory pricing for new users.  

By the way, the MD site appears to be on the way up.
