Actually I don't see how. Since it's been being outsold by combined PS3/360 sales for the last couple weeks it's marketshare should have dropped not risen.
That would be the case if the Wii's marketshare were already 50%, but it isn't right now.
The general case works like this: if the Wii continues to sell in a greater proportion than its existing marketshare, then its marketshare will rise until the two figures match. Although the PS360 sales are over 50% of the current marketshare, the Wii is still selling over 47.1% -its current marketshare- and so its marketshare continues to rise.
The Wii can't hit 50% marketshare under the current conditions: if they continue in exactly the same proportions as the current Other figures, the Wii's marketshare will rise to about 47.5% and then stop. But as the proportions change, so will the Wii's potential marketshare; if it goes back to outselling PS360, then 50% will become possible again.
Complexity is not depth. Machismo is not maturity. Obsession is not dedication. Tedium is not challenge. Support gaming: support the Wii.

What do I hate about modern gaming? I hate tedium replacing challenge, complexity replacing depth, and domination replacing entertainment. I hate the outsourcing of mechanics to physics textbooks, art direction to photocopiers, and story to cheap Hollywood screenwriters. I hate the confusion of obsession with dedication, style with substance, new with gimmicky, old with obsolete, new with evolutionary, and old with time-tested.
There is much to hate about modern gaming. That is why I support the Wii.
