Will Microsoft take on Adobe's PDF with Metro?

Earlier in the year I blogged about PDF software but now I hear (various media reports including this one on internetnews.com) that Microsoft will include a new XML-based document file format called Metro in its next operating system (currently code named Longhorn), which is due for release next year.
