I'm assuming it's now on all the hotels - the Doric Graphite Pillar was previously only released into the Catalogue on Habbo.com prior to the merge (it was sold in February 2008). It was spotted on 3 other hotels, but has now been released for 25 Credits and 25 Diamonds on the Finnish, Spanish, French and Brazilian Hotels at least!
Looks like they will be bringing more rares out - a few weeks ago some laser gates were released on other hotels too; we can't really be too sure if there will be any released on .com? I would love to have full sets of items, but some of those we have already are so expensive and they will never hold their value!
