New Guru forum is definitely different than the old Guru. Does take some getting used to but it is fairly easy once you figure it out.
Too bad that the forum software they use is an utter piece of crap (talking from experience here). I had a (legal!) Invision Power Board 3 running, when I upgraded to IPB4, literally EVERYTHING broke. And that was a full release of commercial software.
Eventually I had to migrate that other forum to MyBB... because that actually had a great and supported IPB4 converter. MyBB is however really good.
I'm not the only one with these issues though, as for example Neowin had issues for over a year following the upgrade and it broke everything on their site - commenting, the editor UI and so forth. It's still not 100% fixed over there, and that's one of the biggest IPB forums around.
That being said, enough about my hate for IPB (though I really used to love it!). Together, we can do everything we want!
