the wii is not popular because it is casual. It is popular because it is a toy, and a rather fun one at that.
Imagine a console that was in most retirement homes. Hospitals would have it for a fun way to retrain muscles and limbs that need to learn how to function again. Every radio show contest and school raffle are giving them away. Office break rooms have them because it is quick stress relief.
None of these systems will ever hold more than 3 games in its disc reader.
Listen none of these places encourage core gaming. Ninty is not going to sell to a tenth of their market any core games they have lined up. This is not a digg, but a support for further points.
Sony and MS are into selling long games that require investment. The gamers want that. nobody in charge wants to see their respective consoles going out the door for contests and such. especially sony. sony needs a 3 attach rate to be profitable.

as you can see from the charts wii is making a shitload of money. High attach rate is due to the geek fans who have everything from rayman and smash to wii fit.
in order to make up for ppc, 360 and ps3 have to sell more games. naturally this is more easily done with more market proliferation. However, that can't happen until price comes down.
ps3 is looking for the fastest way to recoup losses. they are finding cheaper ways to make stuff. same goes for the 360.
These two consoles are trying to make their prices as low as possible because they will sell more games on a platform that is more regualarly purchased.
I'm sorry to make this one final point, but it is a true point.
The Ninty sells because it is solid, that is true, but mostly because it is the cheapest of all the consoles. A game system needs to be 100-250 dollars.
ps3 is on for a supposed 10 year run, so later on it might become a powerhouse console, but for now it is a long way off, and casual games are not the answer. The ninty isn't casual, it's affordable.
