Rondo got released on the Virtual Console today(March 15th 2010) in North America, under the name "CASTLEVANIA: RONDO OF BLOOD".
It's an import release, set at 900 Wii points. By default TG16 games which were Turbo Duo CDs are 800 points, imports 900 points obviously(such as the case with Gradius II PCE). As of now, the only three (originally-on-a-console) Castlevania games not to be released on the VC are Vampire Killer/Akumajou Dracula(for the MSX), Castlevania: Bloodlines/CV: New Generation/Akumajou Dracula: Vampire Killer(for the Genesis), and Castlevania: Dracula X/CV: Vampire's Kiss/Akumajou Dracula XX(for the SNES).
As with most(if not all) of the VC import titles on the Wii, no additional localizaiton has been done. However, I'm sure that won't be a problem for people who played Dracula X Chronicles extensively. That and the fact the Japanese was translated(the files are on the CV Dungeon's page for Rondo) well before DXC got released for the PSP.
