The next vBulletin update should be released in beta by the end of this month or the beginning of the next. That will be the upgrade that will include the new style layout which will screw over our current themes and some of our plugin mods/extra features. However, there should be quite a few new features that should compensate for whatever we may loose. And as far as I know, the arcade should work in vB 4.0.
Shortly after vB 4.0 is released, vBulletin will release their custom cms which we will probably purchase and make Ancient Clan into an actual site again instead of just a forum. But we'll have to see what functionality that program has before we make more definative plans at this point. Just keep in mind that changes are coming to AC... soon.
and I better be impressed with what vbulletin comes out with. *kicks vb*
