It wasn't said that "looking into allowing Html5/CSS3 apps to written in Windows 8"...the way it was spoken gave the impression that is was the only way to do apps. That's the impression some people got. That is what a PR department is supposed to fix, when slipups like that occur.

Same thing when Bob Muglia slipped up at that conference, giving the impression that Silverlight's only position will be in WP7...then Scott Gu fixed it with a PR fix that developers thanked him for.
