Cataclysm Beta: Portals gone from Dalaran / Shatt.

UPDATE: Zarhym addressed the portal removal in the official forums. It looks like class trainers and Auctioneers will be added in Dalaran and Shattrath! You can read the post after the jump.
According to a news post by WoW Insider, it seems as though the portals in Dalaran and Shattrath that lead to the major cities in Azeroth have been replaced by class trainers in the Cataclysm beta. In other words, if you want to pop between Ironforge, Stormwind and Darnassus (just kidding, who goes to Darnassus) quickly, you're going to need to find an alternate route. Obviously, with the entire remake of Azeroth come Cataclysm, it seems as though Blizzard really wants to usher their playerbase back into their home land, so it makes sense to take away some of the comforts that made Dalaran and Shattrath such fantastic home cities.
They do note, however, that with Cataclysm will come some more convenient methods of travel, like Deepholm (a new zone) having portals to Stormwind and Ogrimmar, and vice versa. We'll just have to wait and see what comes next in Cataclysm!
