According to a recent "T for Teen" classification by the ESRB, Castlevania: Rondo of Blood (better known as Dracula X: Rondo of Blood) appears to be heading to the Wii. An OFLC rating of the game back in December already hinted at the possibility of the game arriving on the Wii's Virtual Console (the Japanese version was released in April 2008), but the ESRB rating's description seems to clinch it, citing the "early-90s rendering" of "reddish blood-like bursts."
Previously, unless you were a resident of Japan who owned a PC Engine CD in the early '90s (or, more likely, a PSP owner anywhere in the world within the past two years ago), there wasn't an easy way for you to get your hands on "Akumajō Dracula X Chi no Rondo" (Rondo of Blood's Japanese title). But now, it seems that Wii owners outside of Japan will get the chance to check out the game.
