Was Nintendo's 2008 flop of a lineup merely an issue with perception?

^happy with 4 games in a whole year, my my times have changed (or "gamers")...and that's exactly why third parties are not happy about it, people just buying Nintendo games.

The average consumer buys a new retail game once every nine or ten weeks.  That is the same on the 360, the PS3, and the Wii.  That means the average consumer buys between five and six games a year.  Nintendo published three monster games last year, and a lot of other solid games.  That should be plenty for one publisher.  Third parties should be able to fill out the last few purchases of the year.
