It currently looks like you'll get more direct connections and thus fewer hubs. Some routes will never be direct (rural US to rural Europe) but it's enough to have 1-2 hubs serving those. All major city connections can be direct. However, that will not necessarily reduce congestion for large airports, the NYC area then has to serve more destinations than before (by shifting away from hub traffic to LHR).
