For 2007 I predict that the 360 will see it's lead shrink below 2 million units. 360 and PS3 will not break even. And Metroid Prime 3 will do so-so. For 2008 I predict that the Wii will hit 20 million units before the 360. People will stop discounting the Wii as a one-trick pony. 360 and PS3 will not break even. Beyond that I predict that we will not see an XBox with significant new features before 2009 or 2010. Edit: had to add some more predictions.
