There may be comparatively little difference from what you see today, 
largely because most hosts still have stacks which are poorly tuned by 
default, or host throughput is limited by some other device in the path 
(such as a broadband "router") which acts by default as the constricting 
link in the chain, or the application itself isn't written to take full
advantage of higher speed wide area connections. 

Depending on your point of view, all those poorly tuned hosts are either a 
incredible PITA, or the only thing that's keeping the boat above water. 

If you believe the latter point of view, tuning guides such as
http://www.psc.edu/networking/projects/tcptune/ and diagnostic tools
like NDT (e.g., see http://miranda.ctd.anl.gov:7123/ ) are incredibly
seditious resources. :-)
