I honestly can't fathom why you're looking at this as sales per publisher, and record years and all this stuff. If for no other reason, it depends entirely on what they release and will change year to year. Of course Konami arn't going to have a record year without an MGS, or Capcom without RE, or Namco without Tekken etc.
PS3 and X360 are both set to have record years for software again, so to then conclude that this is the peak year just seems odd and unfounded. Sure, it could be, but it could continue to peak next year? Move and Kinect certainly seem partly designed to 'extend' the console life cycle and drive software sales away from decline, and unlike when the PS2's design began, the games coming to these systems are still all the major franchises. Your method to me doesn't really feel like a sensible way to determine industry-wide trends.
p.s. how the hell did Ubisoft sell so much in 2008 (A non Assassin's Creed year)? Did Assassin's creed sell alot after 2007's xmas or am I forgettng some big hit? :/.
