MSNBC - Is it going to be Flash or Silverlight

One of the big stories in CES 2008 was the fact that Microsoft will be partnering with NBC to provide the online video access for the entire Olympics experience.

What I am wondering about is why the current MSNBC beta video program is being completed in Flash. Should this not server as another golden (or silver)opportunity to push the Silverlight experience.

I did notice, however, that NBA.com has released some pictures using Silverlight!
