CO only uses 3 gates on B and 1 gate occasionally on C. Hardly enough for the entire CP operation. However, presumably DL will start parking their mainline planes on A and likely shuffle the CRJ200s to C with the rest of their friends and leave the 900s on B. With that, there could very well be enough gates on B for the CP operation... not to mention the vacated space by CO on the 1st floor. I think however, it will carry on as status quo.
