Cox tells 1UP that the game was always meant to be a Castlevania title, but the association was removed when it was first announced at E3 2008. It seems Konami didn't want to steal any thunder from its then upcoming Castlevania: Judgment. Probably a good call, considering Judgment's nominal thunder could be stolen by a reasonably large rubber ball.
Cox also revealed some fresh details on the game, most importantly saying that it will not follow the design of most of the recent titles in the theory, abandoning Metroid-esque exploration in favor of more linear action. In response to franchise purists, Cox pointed out that some of the best entries in the series (notably Castlevania II and IV) have been action-only affairs. Of course, it helps that the main character, Gabriel, is actually a Belmont. Head over to 1UP for more details and be absolutely certain to watch the new, extended trailer above.
