If it's split like that and since the hq in Seattle already exists, it's not a new HQ at all - it's merely a satellite office.  Dumb to put a satellite office in high costs places like NY unless the business connections benefit you somehow.  Amazon is heavily dependent on imports from China and the rest of east asia.  It'd be better to place an office in LA where the biggest port in America is.  Or some lower cost city.

The whole point of it was to get further east for time zone changes.
