I think TheHun would already have many other interests within the industry, which maybe don't depend on the TGP's traffic to survive. If so, for the right amount of money he may want to sell it. With a wife and '3' kids (the pages turned blue twice and pink once) he may have reached a time where he wants sit back and relax a little.
However, he is very dedicated to that site - yes he has reviewers - if your gallery gets past them, it goes to him for approval and then you'll get an email with an approval or decline or suggestion what to do to improve it. If that's not dedication to your site.....what is? I think that money is not everything for him, I think he enjoys taking care of that site so I don't think he'll get rid of it any time soon.
I could be wrong - but even if someone buys it - traffic/business dwindles quickly once there are major noticable changes in the foundations of a company.
