Additionally, The Last Story is a new RPG for Wii being developed by Nintendo and Blue Dragon's Mistwalker. According to Andriasang's translation of a statement from an investor meeting, the game is an attempt at a "new form of RPG." The last time Nintendo worked with Mistwalker, the result was Archaic Sealed Heat, which Nintendo didn't bother to localize for North America.
Finally, a Metroid: Other M teaser site has also been newly launched. It doesn't really reveal anything about the game, other than confirming its summer 2010 release in Japan. Interestingly, the game doesn't appear to use the traditional Metroid logo, opting for something much plainer.
