USA is looking good as well. The best teams I've seen so far: Nederlands, Costa Rica, France and Colombia.
This is my take on the next round:
Brazil will get by Chile but with difficulty
Nederlands face a more challenging game vs Mexico, I think the tricolor has yet to concede a goal, Nederlands via penalties
Colombia will probably face Uruguay, I expect the cafeteros to do well and move on to the next round
Costa Rica vs Ivory Coast, ticos should prevail
Argentina vs Switzerland, I don't expect an upset; Albiceleste to advance
France vs Nigeria, les Blues hands down
Germany vs Algeria, die Mannschaft sweating
Belgium vs USA, upset and Yanks will make it to quarters
Best World Cup in a long time (sorry to see England go early though)
