Tecmo(are they a Microsoft 2nd party?) they hate nintendo systems...
Konami has not put a good game on an N system in a long time... why don't they put PES on Wii? Oh well, they are losing at least a million in sales.

Besides the N64 capcom has been good to nintendo, I buy alot of their games : )

Tecmo is a good example -- they have put Super Swing Golf on the Wii (And it has bombed, I believe), but their main franchises are Dead or Alive and Ninja Gaiden, and neither are particularly well suited to the Wii.

Some companies like Tecmo and Epic (as Eugene mentioned) have crafted a particular image around being "hardcore," with top end graphics, lots of violence, and a very healthy dose of testosterone. Not that the Wii can't have such games, but the PS3/360 are almost exclusively and entirely directed at that market. 

 Hmm, didn't they make a Ninja Gaiden game for the DS? I would have thought out of the handhelds, it would the PSP. They also have Rygar for the Wii. Granted, it's not really what we would expect but as we go into 08 and 09, Tecmo might be encouraged to create a new IP for the Wii.

first thought was Konami but maybe its Midway the way they hardly try but seriously when was the last time Midway made a AAA grade title???

Was it MK2?

Well, probaby just a majority of "hardcore" (meaning fan base of whoever it is playing and loving their games) pc oriented games studios wont make a Wii game. I cant imagine Id software, Nc soft, Bethesda, or Bioware making one even given the opportunity.

 I would think Stranglehold but that flopped when you considered the amount of money the'd poured in.

And then there was the crappy Blacksite: Area 51 

 Pe2008 is coming to the Wii. they even put some effort in the controls, just seek it up.

http://en.wikipedia.org/wiki/Untitled_Sonic_RPG if they'll make a DS game there is no reason they wouldn't make a Wii game.  Bioware is clearly willing to branch out into more family friendly development.  I would be very surprised if they don't have a major Wii game this generation.

http://en.wikipedia.org/wiki/Ninja_Gaiden_Dragon_Sword same goes for Tecmo.

Wait, isn`t Fatal Frame from Tecmo? I still think they are not very happy with the idea of making Wii games, but that is business.

http://en.wikipedia.org/wiki/Fatal_Frame_4 yep in colaboration with Suda51 and Grasshopper studios. Fatal Frame is actually one of Tecmo's biggest franchises. It's also a big deal because this game was announced for PS3 and 360 but canceled to make a Wii version instead. Similar to Monster Hunter 3. So, Bod cross Tecmo off the list.

As a side note, people who like survival horror should look out for this one. Basically the idea is to photograph the undead. It's one of the most creative franchises in the survival horror genre and Suda should be able to do wonders for what's already a great idea.
