Oppose, slightly.  While I agree that the current use is not necessarily primary, I do not see how moving this will result in a net positive. eth 
With the city article averaging at least 300,000 more readers a month, wouldn't it make more sense to have "New York" redirect there? It would be a net positive if the least amount of readers are displaced, and given that the city seems to be the primary usage, especially internationally, I think that redirecting "New York" to the city would do just that.
