According to an article by Mary Jo Foley in Cnet, the new Microsoft Office 2013 will be able to support third party apps. http://news.cnet.com/8301-10805_3-57489105-75/microsoft-office-2013-goodbye-to-adds-in-bring-on-the-apps/
To this end, Microsoft has offered 80% to the producers of such apps, and only keeping 20% of the revenue themselves. They are definitely taking a cue from Apple and Google and adapting their product to the iphone, tablet market. Too bad they didn’t think of it themselves first :).
