The only person working on Samurai Shodown RPG is Deuce and he had some unfortunate problems with this site's administration and decided never to return...
Unless you're saying that you're willing to bring over whatever news he's posted elsewhere, which then, that would be pretty cool, I suppose.
As far as I know, Deuce is still doing commercial work alongside XSEED at the moment helping them bring over some Falcom games for the PSP. Until his obligations with them are finished, SSRPG will be on hold for a short while.
