Ivorise - It's a little too early to tell on that, I think. : ) A single set of each color being featured for all to see might actually help raise popularity of the sets, but it will all depend on how often they get introduced.
Like accessories, there will always remain a relatively steady demand for items that are rare enough to be featured in that section, and they bind permanently. In the meantime... I may watch and see what happens!
@Rubyeclipse: I guess you should start selling your 1st edition rose regalia sets now before more enter the Featured Auctions.
Yes, truly time will tell, this game has changed alot in the past few weeks.
