Microsoft to Pit 'Metro' Format Against Adobe PDF, PostScript?

I doubt that. PDF format has its market place and whatever competition tried to promote was a failure comparing to the popularity of PDF format. By reading the following article, my mind goes to Open Office. Open Office became one of the most popular text editors, among other operations. I am not talking about editing text but saving it into an XML based format, available everywhere. Of course that XML is the "new wave", of course that portability, fast search, smart query and web related items should be based on XML... Microsoft felt all these and made XML the new core of it's products. All of them aim XML, why not an XML based document format?
"Metro" - the new document format is at the beginning... will it take over and win against PDF? I don’t know, but I am already trying to imagine what Microsoft would do to enforce it...
