Not sure how much it helps, but I spoke with an ORD gate agent in October and they told me that service was going to be reduced to 1x daily for most of 2015, and that the DAL-ORD service wouldn't be launching I'm April 2015 as announced during the Love Field campaign. He did say that service would likely restore to current levels at the end of 2015 once new planes were delivered, and at that point they'd reconsider DAL-ORD service too.

From this convo, along with other piece of info acquired throughout the past few months, it seems like the fleet additions in 2015 will be mainly used for restoring cuts to frequencies (like ORD). Ultra-optimistically one would think that cuts (erm, "suspension") like PHL would be restored, but that is less likely. And of course service to Hawaii. I can't imagine it being more than 1d daily each from SFO and LAX, but I am unaware of exact plans.
