Canon release schedule

Ok, we all know that Apple likes to stay on a somewhat regular update cycle with their products. Does Canon do the same thing with their DSLRs? It looks like the release dates are the following for the Rebel line:

Rebel XSi (450D): January 2008
Rebel T1i (500D): March 2009
Rebel T2i (550D): February 2010

Is it to be expected that they will be releasing an updated Rebel early next year? I'm starting to really like photography and would really like to upgrade from my Rebel XT that I started out with to prove to the wife (and myself) that I would actually stick with it before spending a bunch of money on it. I was just browsing Canon's Refurbished site and they have the T2i with the 18-55 and 55-250 lenses for $709.98 which is really tempting, as I already plan on getting the 55-250 even if i stick with the Rebel XT.

What would the T2i be able to do that your XS can't?

Actually it's the XT (350D), 3 generations prior to the XS (1000D). I bought it for just $250 for a whole kit to get started. That was about 6 months ago, so now that I am really getting into it, I feel it's justified to spend a little more money to move into current tech. The main thing that I would like from a newer body is higher ISO quality and all around image quality. My XT tops out at 1600. The video would be a bonus as well, although at the moment it's not a necessary feature for me.

And maybe I really don't need to upgrade the body. My lens collection is pretty small at the moment, but I plan on adding to that in the near future. The kit I mentioned with the T2i would go towards that goal. Also, if I did upgrade, I would sell the equipment I already have, and could probably get more than I gave for it.
