Currently in wrath of the lich king you can only craft rare quality pvp gear which is easily replaced by much better quality badges and honor rewards. As more gear was released throughout the expansion the craftable PvP gear value decayed exponentially. Although it is STILL possible to sell the PvP gear for profit on most servers, imagine if it always sold as well as it did at the start of WOTLK. Instead of being semi-frequent sellers for marginal profit, these items will remain in high demand throughout all of Cataclysm.
Obviously Cataclysm PvP items will not be best in slot gear by any means, but they will always be the same distance behind current bis gear so the value should remain relatively the same instead of decreasing the way it did in wotlk. You'll have some time to level your professions, probably a month or two before Cataclysm's first arena season is announced, before people start purchasing the new pvp gear.
Did you have any experience selling the pvp craftable gear in wotlk?
