I believe that they are still testing out the alternatives before declaring a chain standard.

It could be that they will be differentiating between "brands" PH, Andaz, GH, HR, HP, HP/hh.

This could explain the June Jacobs at the GH NY - the same brand was in the GH HKG last month.

There has been reports of KentMD around - at HR New Orleans and I believe at 48Lex.
