Exactly my thoughts. Only thing that comes to mind for MDW is its neighborhood location. I believe many of the neighbors would like to shut it down and maybe JetBlue doesn't want to fight that battle. Also, with the shorter runways than ORD, are weight restrictions potentially an issue for the 320s?

Overall, ORD seems a bit odd. Only thing I see going in its favor is that its the largest market in the US where B6 doesn't have a presence. There are definitely lots of people, but I think grabbing a decent market share in this market is going to be tough. Its been fairly well developed for years now (with other hubs not too far away in STL, DTW, CLE, and MSP) and short of maybe a lower price, not sure what B6 can really bring that isn't being offered now?
