Snk, I think it should stay for good. It's not like it's a holiday area, and the docks are finally filled with activity. PLUS, the pirate items are cool. All the new players want those items. I still want like three of them. I think it'd be unwise to remove them. Seriously.
New areas like this should have their own available arsenal for sale. It's the same with any rpg. What, are you going to release a ninja cannon that fires real ninjas... Then remove all the items from the ninja town? Might as well rename it ghost town.
