It may seem peculiar to those of us that savour the E3 bubble, but it's not as big a deal globally as some may think. Nintendo's Japanese homeland is an example - there's an awareness of E3, but probably not the laser focus that's applied in the West.
For those that found it all a bit much to follow, or have lost track of all the events that took place, the following two videos combine to give a rather handy 10 minute summary. The first is all about the Nintendo World Championships, and the second is a presentation around E3 in general by Reggie Fils-Aime.
