This concept, is frankly, apalling.
Under no circumstances should wikinews become a place for wikimedia to issue press releases.
Namespace seperation is a techinical solution. Read that as many times as it takes until "technical" is so firmly ingrained in your brains that you realise what it means. Technical. IE. Has nothing to do with politics, or how wikinews is percieved. If wikimedia wants wikinews to be no better than a Chinese paper then fine, go ahead, do that and watch it die. Simply because press releases are delegated to another portion of the site does not hide the fact that they will definately appear to be from wikinews itself and therefore be seen as official wikinews news. Blatant POVism. Blatant. Corporations have a subpage for press releases, why isn't that sufficient for wikimedia? Do you people _really_ think this is going to help wikimedia popularity?
If you're a big PRC fan then I'll give you another example. The US's DoD has a "news service" out now complete with it's own channel. Not surprisingly, no one, not even many US soldiers, takes them as a factual news agency.
