No significant new updates on this game - but without any announcements the release dates for various versions have quietly slipped further and further back. The neogeo version was supposed to come out in June originally, I think it's supposedly on for August or September now.
The DC version is not ported until the neogeo version is out for a couple months (in case bugs are found), so we probably won't be seeing the DC version until this fall.
I suppose this means we might not be seeing Ghost Blade until 2014
