At first glance the listing seems designed to lure the collectors or fans who don't know about the reissued set. If he has photos of the actual item, he should have included them rather than just tell buyers to ask for them. On the other hand, he could just be lazy or not wanting to pay extra gallery fees. But to use the old set number and not once mention the DS one is highly suspicious and deliberately misleading, if indeed this is set 6329 he's selling. The number would be clearly marked on the item when he originally received it. Maybe he has opened it and placed the contents in a new unmarked bag.
You paid well in excess of the purchase price it will be when it becomes available in the US and that must hurt. It happened to me a few times when I was first starting to buy Playmo on eBay too.
I hope the seller has a conscience and that you have success getting your money back.
edit:Just noticed this near the bottom of the page so I think you will be OK if you act quickly.
