QuietID,
First of all, you need to dispel all personal illusions of the possibility that Nintendo will go third party. Sony, with the billions they've lost (4.5b), is more likely to depart the console race than Nintendo. Nintendo made so much money in the last two years alone to nearly eclipse their earnings from the DECADE prior to 08, while Sony is on the verge of losing all profits made from both the PS2 AND the PSX eras.
So cast the third party drivel from your thoughts, okay? It'll never happen now.
Second, Nintendo's hardcore titles complement its casual games, and have equally contributed to the success of the Wii. Mario Galaxy, Twilight Princess, Metroid Prime 3, NSMBWii, SSBB, MKWii, Endless Ocean, and upcoming releases such as this one help to fuel the Wii's success and contribute to its quality lineup. Let us not forget that it is a hardcore Nintendo title that was the hottest game this Xmas and helped to push the Wii to break the PS2's single month sales record last month.
If you don't like the Wii, its games, or think that there are better offerings elsewhere, that's fine. You're in the minority, however, like the rest of the Hollywood gamers on this site. I personally think the Wii caters to all my desires as a gamer, and it only takes a brief glance at the OP to understand why.
Poor Wii, you say? LOL, no...poor HD fanboys.
