I expect a few of these things:
-level cap increased slightly (even for a game that -rightfully- claims skill is more important than level or hours played, 20 is still a really really low level cap. I suspect that the reason is so that they can introduce new level caps on future expansions without ending up with ridiculous levels... like 200 or whatever. The next level cap will probably be 30)
-new professions/skills (it's a brave new world, there will obviously be a new culture and with it new types of jobs and new types of magic/war/etc.)
-more pets (there is a menagerie in Cantha, that's where Jarrel the animal tamer sends the pets she takes from you)
-new enemies (duh...)
Any other ideas based on clues from the game?
