Part of a recent financial report from the publisher contained forecasts for forthcoming releases, as spotted by a keen-eyed Siliconera commenter and posted on NeoGAF. The estimations for Avalon Code's were notable, as they included figures for the U.S. and Europe, which in turn tells us we'll be getting the diary-keepin' ARPG here in the west at some point before March 2009.
Alas, we'd only just finished chest-bumping one another and shouting stuff like "HELL YEAH" when our excitement was tempered by the realization that Luminous Arc 2 and Steal Princess didn't have figures for the U.S. or Europe. This (probably) means that those games won't be localized this financial year (despite our hopes for the former). That's not to say they'll never make the trip across, of course, but for now it's one in, and two out.
