Honestly this might put pressure on Hyatt and Hilton to merge. Hyatt is staring to grow its select-service chain with Hyatt Place but are they growing in that area fast enough? Hilton has the low-mid end covered very well, some high end brands but really not enough now to compete against a Marriott/SPG combination. I could see this leading to talks between Hyatt and Hilton resulting in the following brand mapping.
Park Hyatt - Waldorf-Astoria
Andaz - Canopy
Grand Hyatt - Mixture of Hilton and Conrad
Hyatt Regency - Hilton
Hyatt - Hilton
Hyatt Centric - Mix of Hilton and Doubletree
Hyatt Place - Hilton Garden Inn
Hyatt House - Either Home2Suites or Homewood Suites
Hyatt Zilara and Hyatt Ziva - Hilton All Inclusive Resorts (or Curio Collection)
Hyatt Residence Club - Hilton Grand Vacations
