A new patch is coming soon. Highlights : A mount for you alt at lvl 30, and new bags. For 1200Gold you can buy a 22slot bag at an npc named Harris Pilton ;). The idea behind this is probably just to introduce a new money sink and try to get people to play a bit longer by letting them grind dailies for a few more gold for these bags.
