Frankly, it won't make much difference, or at least it shouldn't.
50% is nice as a psychological milestone, but knowing that Wii development budgets for an AAA game are much smaller than 360/PS3 budgets, and knowing how it's already so damn near 50%, the economics of the situation already say that developers should start putting their games on the Wii. That is unless they're being spoon-fed moneyhats from Sony/MS to keep them alive.
We are already seeing developers which made wrong bets fail hard in their financial reports. They can either continue pretending they're rock stars who don't need money and downsize / go out of business, or they can wake up, smell the coffee and thank Nintendo for making an economically viable platform.
