dude dont be a ****ing noob, its not the "core" that matthers.
Thats a bit of a hostile response, don't you think?
And if by "core," you're referring to the SoC, yeah it kinda does matter. The tegra 2 is a tad outdated, its architecture being a big part of it (A9). The Tegra 3 was a nice upgrade on Nvidia's part, with the Samsung Exynos 5 being even better than that. I'm sure someone with even more technical expertise could explain more in detail on the differences, but the architecture itself is a good indicator.
Now on to personal experience. I've put my Xoom alongside a Nexus 7 and my Galaxy Nexus, all running 4.1.2 and yeah, the Xoom is noticeably slower. I can't wait to see the Nexus 10's performance in person. No one here is saying the Xoom is **** or slow or whatever. But it is, gasp, slower than devices with hardware that is fresh and not 2 years old. Newer technology is better, who knew?
So yeah...no offense but given the delightful way you went about disagreeing with me, I'd say you were projecting just a tad.

That being said, if you look back to ICS, the 4.0.1 code dropped... and no Xoom support. Then the 4.0.2 code dropped... and no Xoom support. It wasn't until 4.0.3 that the Xoom gained AOSP support. I wouldn't be suprised to see the Xoom supported in a 4.2.2 (or later) release. The Nexus 4 isn't even supported in AOSP yet, for goodness' sakes! It will probably be someone's 20% time project and it will happen eventually.
The difference with those instances and now is that the Xoom was projected to get all of those, it just took a bit of time for it to hit AOSP. According to the google groups statement, the Xoom is slated to stay on 4.1.2 (I forget the actual quote). Now of course, that could mean, as you say, that it might just be a while for it to hit AOSP, but I think that's being a bit hopeful. Hopefully we'll get an official word on it soon but I think thats about it, at least with regards to AOSP.
And honestly, the Xoom had 18+ months of official support. For those that remember, 18 months was what Google wanted manufacturers under the Android Update Alliance to go by for supporting devices. So they've met their own target and then some with regards to both the Xoom and the Nexus S.
