I honestly think we will begin seeing a transition back to mainstream gaming for nintendo (they were never core save for a few franchises like FE)
I think they are in phase 2 of 3.
Phase 1 was capture Nintendo gamers and peak the interest of Casuals. Zelda at launch did a good job of this, then Metriod and Mario (also brawl was supposed to be a cmas 08 title) in the First year sealed up all the Nintendo gamers, then phase 2 which were are in. Capture the casuals, it is working imo better than phase 1 did. WiiFit, MKWii, Wiimusic, WiiSports resorts, and other stuff.. Phase 3 will begin next year as they build on what MKWii is starting (tradtional game selling to casuals)
One they have completed there 3 phase plan they will then follow a more traditional pattern to get some HD gamers who see no reason to buy a Wii right now. 3rd partys will have to help in this. I think it will succeed in Japan with what we already have announced, the west is still in question.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
