And Carnival Games got more advertizing thatn those games. It's not rocket science. If developers want hit games for the Wii, they should market it, like just about every hit game. 

The cart before the horse is not quite the analogy I would have chosen.  The "Chicken and the Egg" analogy fits so much better.  Developers want assured success for their games before they put them on the Wii yet need they can't see that success until other developers begin putting similarly targeted games on the Wii.  More than anything, the Wii needs more developers willing to take the plunge right now.

I would say always.  Good marketing will result in more copies sold than bad marketing.  That is a statement of fact.  However, the profit from those extra copies sold must cover that marketing.  If developers are approaching the Wii as a cheap alternative, they're going to try to minimize their investment at the risk of possibly hurting their bottom line.

Well the thing is that applies to HD games as well. They don't just sell on their own. They also have huge marketing budgets, which often accounts for why so many have to be sold. With the Wii, having lower development costs, marketing wouldn't have to be as big to ensure the games ell enough.

Of course those are maybies, and I'm hoping we'll see the first developers plunging this fall, to see if this is the case. 

We'll see soon after the beginning of next year.

If Nintendo approaches the 60% market share, we can assume that a portion of those owners are from the expanded markets (first time console buyers) who usually tend to buy fewer softwares. So if the ratio is 4 HD consoles to 6 Wii(s) chance for profit is still equal on both. But if the ratio reaches to 7.5 to 2.5. Then say goodbey to HD consoles.

Actually, the cart before the horse is correct and chicken and egg is nonsense.

There is no chicken and egg, as there are big games selling on the console, the console itself sells like crazy too.

Games have no more chance to sell more on the other consoles, like the big flops we have seen already.

And what is asked is not "If developers are approaching the Wii as a cheap alternative". They're already doing that. They'll have to do better if they don't want to become irrelevant in the case the Wii reaches 50%+ market share.

Actually, they'd better hurry, it will soon be too late for them. Right now, all they can do is tripping over themselves to develop for the Wii, as it's already too late.
