IGN is reporting that Nintendo of Japan has revealed the Wii lineup for the rest of 2007. Japanese Wii owners can breath a little sigh of relief – high profile titles Mario Galaxy, Super Smash Brothers Brawl, and Metroid Prime 3: Corruption are slated for release in 2007. North American gamers will have to wait for confirmation on these titles, but a Japan release in 2007 would seem to be a good indication that the same games are on their way to the US as well, particularly Metroid. Nintendo, more than any other hardware manufacturer, relies heavily on their first party line up to carry the console, so getting 13 first party releases, albeit with non-games like Wii Health and Wii Music will help drive demand during the holiday season. Of course, this might be moot if Nintendo can’t increase their hardware supply as they have been promising. With third parties still seemingly adjusting to developing for the Wii, Nintendo is going to be the prime software supplier for 2007.
