One would have to assume that, once the switchover occurs, searchers using Yahoo will continue, at least initially, using Yahoo. So, in theory, Bing traffic should increase. Whether that will translate into organic search traffic for individual sites equivalent to what Yahoo was yielding could be anybody's guess.
Also, the article refers to "Bingbot". I don't recall ever seeing a crawl by Bingbot, just msnbot. Am I missing something?
