A few comments:
1) Glad to see that the office project in Southside Works is going to finally happen. That ugly dirt lot by the hotel is sorely in need of being developed!
2) I'd say the Fairmont Hotel is very nearly equal in stature with the Ritz Carlton and/or Four Seasons, so Pittsburgh does have one luxury hotel already. Of course, I do see either a Ritz or (more likely) a Four Seasons probably coming to town in the next few years, especially if the economy of the region continues to improve.
