i play starcraft 2 as a hobby.. the lag from different regions is more determined by the route that the information takes around the world as the amount of information being sent is not much compared to the bandwidth that is available these days with current internet speeds (i am in adelaide).. I know that MMORPGs generate a heck of a lot more information than a RTS BUT i would say that the route the information takes around the world is still more important than the bandwidth..
