Yeah, the World Cup. For one John Barnes related reason and another I find myself less in love with football than is usual this season, but come the summer I'll be watching every single match. Nothing compares to it. When the European Championships are on I struggle to care about any match not involving England but when the WC is on, there is nothing I won't watch.
As for the 'stopping a whole nation' argument RE the Superbowl - step into the street in England during any England WC match and see how many people are out there.
