ABC has all the BCS games, I believe. In the fall programming synopsis is,
"...ABC Television Network president Alex Wallau announced on Sept. 25 that the most-watched and highest-profile sporting events of the year, including the Super Bowl, games of the National Basketball Association finals and the Stanley Cup, will be broadcast in HDTV on ABC this season. ..."
I would think that at least the Fiesta Bowl, and likely the Orange Bowl and Rose Bowl fit this filter of "most-watched and highest profile sporting events of the year".
Why haven't we heard anything definitive yet?
