Its because there hasnt been any good software on the wii in a while.. they hyped super mario galaxy like crazy, they hyped super smash bros like crazy, but its been a while.

There's a few reasons:

1. The majority of the readership of these "journals" are gamers who own a 360 or PS3

2. The upcoming Wii games are mostly Japanese and it's much easier for an American magazine to write a story on an American game rather than a Japanese one.

"Journalists" are usually casuals or fanboys.

The only coverage those games get are from unbiased core journalists.

If you mean games like M:TDB?

Actually guys the majority of journalists have a PS3, 360, and a Wii.

What's a good Wii game?

There are 50million users looking for great upcoming wii games on the same magazine!

By the Way: The List of all good Wii Games (sorry, only in german)

And here are the List of all good games for all consoles (average press reviews):

Many of the gaming's community "ayatollahs" are treating the Wii like it's not even a "serious" system: for them, it's a cheap toy and a "fading" novelty appealing to a mass market of people who usually don't buy consoles and games...

Of course, the fact that 5 millions of people bought Twilight Princess very early in the console's life is irrelevant... a "very healthy core market" exists when there are 10 millions of Halo or GTA buyers, but not when there are 5 millions of Zelda buyers: a very famous double standard in the industry...

Another "classic"? Nintendo can do no good... Nintendo "core gamers" had to be ignored last gen because their console was third and "kiddy", now they have to be ignored because their console is first and "casual"...

And when good games are finally released on Wii (yes, miracles do happen sometimes, even in the middle of all that negative spin), what's the usual reaction?

You have 10 to 20 "ayatollahs" doing developper's interviews, each of them asking: "your game's so cool, why don't you release it on PS360 rather than on a console for soccer moms where your game will hardly sell?".

Of course, after the 20th question, many people in the industry begin to fear they've made a mistake with their Wii development strategy...

Fact is, many "journalists" and even many developpers want the Wii to be a totally separate market, a market not made for the "hardcores" because the "hardcores" are supposed to buy the games that have been planned for a long time and already costed millions and millions of dollars of investments... Wii is for cheap efforts made for "ignorants", and for nothing else...

And of course, if only 20/30 interesting and creative "core" games are made for the system, as opposed to the 200/300 high-budget efforts on the PS360, many (very fanboyish) "core gamers" will think the ayatollahs are right, in a kind of weird self-fulfilling prophecy...

To end the cycle, the same "journalists" will often ignore these 20/30 games, or at best treat them with a lot of condescension, makin' them sound "quite nice for visually weak last gen efforts full of waggle: too bad they're released on a console no serious gamer could care of"...

Then they give these a "fair review" with a score somewhere between 75/85, and use Metacritic to prove that most other "allatoyahs" agree, in one of their "deeply thought" editorials: and that's it, then they're proud of a job well done, thinkin' they're doing great for the future of this industry...

The good thing is that 99% of the Earth's population don't read these guys, and don't care at all about all the nerdy fanboys found on the net... they buy a console for the kids, or for the whole family, or for themselves, thinkin' about the fun it may bring, and that's it... last gen, the PS2 was "the thing to have", now it's the Wii, and who cares if the ayatollahs are frustrated with that situation?

Certainly not Nintendo, makin' billions and billions while the "competition" and their "healthy market" stay desperately in a red zone where only the biggest of the blockbusters survive...

Seriously, they don't actually like the system. When you deduct points from Super Mario Galaxy for the co-op being "an afterthought" or from Mario Kart Wii for "being too casual" and "based on luck", certainly something is wrong.

Of the games you mentioned, i agree that silent hill, muramasa, and tatsunoko need more hype, but i just don't care for the rest.
