This may sound unusual, but I'm not sure Nintendo needs to advertize Metroid Prime all that much (at least in 2007) ...
As sad as it may sound for the dominant console, Metroid Prime 3 will be the only game in 2007 on the Wii that has a focus on first person shooter elements that is done particularly well; there may be a couple of other shooters released but nothing on the level of Metroid Prime 3. By the end of 2007 there will be at least 6 Million Wii owners in North America of which 1/3 to 2/3 will be looking to own a high quality shooter in the first person and Metroid Prime 3 has no competition..
I could be wrong, but I expect that Nintendo Wii start advertizing Metroid Prime 3 just to constantly remind gamers who are picking up a Wii that it exists ...
