Red Steel 2 for March 23, 2010, according to the publisher's site. Ubisoft mentioned the release window last July and didn't include Red Steel 2 in its recent delay announcements. We've contacted Ubisoft to confirm the date.
The Wiire notes that Ubisoft slashed Red Steel 2 sales projections by half -- to 500k expected units sold -- during its financial update last week. Hopefully, the MotionPlus-required game has worked out its control issues in the six months of extra polish time it's received.
