"Wikipedia for news" might be a brief statement of the purpose of Wikinews, but it isn't an attempt to solve the problem I'm concerned to solve. Wikipedia made encyclopedias better by making a giant encyclopedia. Wikinews didn't make news better...in any way. What we want to do is actually organize the news, including the "long tail" of citizen journalism, into "small pieces, loosely joined" in the form of one-sentence fact summaries. The result will enable a scalable community to co-author a truly useful, complete, and giant selection of the news, without the noise and confusion that besets the news today. So that's the difference.
