Format looks similar.
They both use recent versions of php software, or maybe vbulletin, I can't hardly tell the difference.
That's a lot like getting a 1974 Chevy Vega out of a junkyard, propping up the mechanicals enough that you can drive it home, and then spending a couple thou on a big ass touch sensitive screen on the dashboard so you can use GPS to find your way there.
However, it looks like the archives and the previous forum structure is still the same once you figure out how to navigate. The link someone mentioned about "read about the new setup HERE" is a bad link, though, and takes you to an error message but doesn't really log you out.
I was more used to the previous layout and I'm not seeing how anything's been improved, so it's kind of a "meh" for me.
