Sam Kenedy over at 1up.com has posted some quick impressions of the playable version of Castlevania Symphony of the Night being showcased by Microsoft at CES. While it seems that it's been given the usual Digital Eclipse conversion (read: same aspect ratio with borders), he says that the gameplay and the audio are spot on.

You can read more of his thoughts here. Also you can check out a gameplay video here (Which Sam is quick to state isn't him playing).
