One of the newest features that I know I am looking forward to is a concept that Blizzard has only recently announced. Passenger quests will part of the new game mechanics being put into play as part of the upcoming expansion in WOTLK.

In this new type of quest certain vehicles and mounts will be able to carry passengers to allow for exciting new escape versions of quests. In one quest you will be a passenger (the NPC will be driving) during a daring escape. As you flee your pursuers the Worgen you will have to throw explosives to slow them down and keep them from stopping you. Another quest will have you taking to the skies in a new type of flying machine and searching for the survivors of some catastrophic event that has befallen them.

With these new quest features the new expansion is shaping up to be one exciting new adventure. In my opinion if these things come about as Blizzard says they will we can expect WOTLK to be a much expansion then even Burning Crusade.
