The Paddock has been part of the planned resort from the beginning and is included on all of the maps and detailed plans. The three original "areas" are Congress Park, The Springs and The Paddock.
To my knowledge,
DVC has not announced a name for the wooded area just added for Phase 3 or the resort. A couple of the buildings for Phase 3 have been added to the Paddocks, but it appears that 4 buildings will be in the wooded area on the golf course.
