To be honest, Korea and Japan have invested in their own infrastructure for a long time already so any attempt to catch up will undoubtedly take a long time. I wonder though if people may be overestimating broadband speed in some countries. Sure world leading Korea has access to 100 Mbps broadband and is already talking about 1Gbps broadband by 2012 (costing them a cool $24B to do so). But just as Virgin here offers 50Mbit broadband with 200Mbit on the way, the average may well be a bit more modest: http://www.speedtest.net/global.php#0
