In looking at my flight this afternoon, it appears that DL may have renumbered the gates in Terminal 2 to create a virtual "concourse C". I am departing out of C62 with Terminal 2 listed below that.

Anyone know if this renumbering is true? I can't locate this on any of the airport diagrams on delta.com or on the PA's website and would like to scope out which gate is which in this new layout.
