I’m not saying it’s impossible, but if Microsoft does get a demo slot on stage during the iPad 3 keynote, Microsoft would be getting much more out of it than Apple.
In the technology bubble John is spot on, but many normal people1 view the iPad without Word, Excel, and Powerpoint as a entertainment or consumption only device. Even though Apple has demonstrated that the iPad is used to create content with apps like iMovie, Garageband, and the iWork suite most normal people1 haven't heard of those apps. They have heard of Microsoft office though.
I feel that an announcement for Office on the iPad would be mutually beneficial to Microsoft and Apple. Microsoft would finally get their most profitable software brand on the most popular computing platform available today and Apple would get one more bullet point to prove to the world that the iPad can and should replace your traditional computer.
