Arc System Works has been fairly faithful in bringing its BlazBlue games to the West. One game in particular that hasn't been localized, however, is BlazBlue: Clone Phantasma, released in 2012 on the Japanese eShop for Nintendo 3DS.
Although Arc System Works has hinted at a U.S. release since 2012, since then the studio hasn't had a ton to say about it. When contacted to inquire if the plans to localize the game were still on, ASW stated that plans for a U.S. release were still underway, but there were currently no plans for a European release.
Arc System works also commented that it has no plans to localize its series of Escape Adventure games, which are developed by Intense Corp and are mini visual-novels.
