There is another variable to the equation. G rotates ads in its Adwords program, while Overture does not. To appear on the top listings you need to pay Overture top $ if you are in a competitive marketplace. This is not necessarily the case with Adwords. Assuming that Y will provide us with the top listings as well, those of us in the right niche could be substantially better offer with Y, at least in the short term. Percentage wise they could pay less than G, but they could allocate to us many more expensive clicks than G does.

“The amount of advertising space is NOT going to DOUBLE just because Yahoo introduces a contextual ad program. Websites will have EITHER Adsense or Yahoo, not both at the same time”

Freedom, you have a very good point in saying that. However the exposure that Y will give to such a program will be such that it will substantially increase the number of publishers, which makes me still conclude that for most of us this will be a disaster.
