Why does this list and method need to be static? There is no obvious benefit from what I see. Static variables do not get sent to the view state. Make this list an instance variable and move your controller method to an instance method as well. Otherwise, this will need to be javascript remoting and the javascript will have to handle the data. @future methods in visualforce controllers should typically only be used when you don't the need the information back from the webservice call. Since you do need that information, you should not use future.
