To my knowledge, Dragon Lord was the only item to be put back into the shops. It was for Nox 2011. Other than that, there was an item raffle where several "rare" items were re-introduced (such as Japan Items, Anka set(s), etc. I'm not sure of any future plans for any possible re-release(s).

And the thread Espy directed you to is a good list of stuff, also allowing you to see the poses of the items as well.
