I'm in the "industry" and I have no idea what you're talking about.Xenforo would have been a way better option than this from what I've seen so far, but I'll sit back & see what happens.
So what is it that you do for a living and what reasons compel you to think that Xenforo is a better option? Also be sure to explain how you would pull off other site features that exist such as the video archive quickly and easily without having to spend significant time writing custom code. Also, be sure to explain what kind of a community is behind Xenforo, and let me know if it has extensive plugins/modules that would support quick implementation of new features. Also be sure to explain why Drupal is a bad solution, but be sure to fully understand the reach of the platform before doing so, along with its capabilities.
I run a pro wrestling youtube & forum, which both literally pay all my bills & my leisure life. Both can be found below,

Everything you could have ever wanted could have been achieved through Xenforo & their page system. I didn't want to say it before, but I'm going to be completely honest with you at this point: I think you have just put the final nail in the coffin here. vB 3 is old & outdated, but this is just taking forty steps back for no reason. Great, you have a video page (that could be achieved in a better fashion through a few different add-ons on Xenforo btw), but you have just made everything else about the forum inaccessible.
Forums are about social engagement now more than ever. You can't just have a forum with a forum list anymore. They have to be able to keep up with Twitter & Facebook as a place that people even want to spend their time & this forum looks like one that would be released around the release of Halo 2, which isn't a good thing in today's market.

I'll be honest that when I first heard you were going to upgrade the forum software, I was excited because I thought, "there is no way he'll pick anything other than Xenforo." Going from vB to IPB would have been like going from Halo: Reach to Halo 4, and there is really nothing else on the forum market that is growing as fast nor is as interactive in both the community itself & the software than Xenforo. Heard you were doing this Drupal gimmick & knew it was done there. I understand that you take a community college class for Drupal or whatever, but I think even you know somewhere in your head that this wasn't the best decision.
Tack on the fact that you killed all the SEO to this site that had been built up for years.
I don't know man, seems like a bad choice to me.
