Honestly from a completely unbiased point of view, all three companies had great conferences. Games is what it was all about, and games is what we got. Halo bundle was sweet. Anything with Uncharted is going to look and feel amazing, MGS is just that. Solid. Good indie games from both sides there. Nintendo had a lot of their big names shown up this e3 with Zelda looking fanastic. IMO while their 1st party stuff always looks badass, they still need to get more 3rd party support or they won't catch up stateside as most casual homes are content with keeping their wii's from last gen with what's out.
Ubisoft stated they are sitting on complete WiiU games waiting for Nintendo to hit a sales number before they release, and games like Watch Dogs are still en route. Plus, one of the best games on that system (Bayonetta 2) is a second-party title (third party dev, first party funding).
Nintendo doesn't really need to 'catch up' to Microsoft or Sony to be successful--they're playing a different game as it were, akin to Apple vs. Android in the smart phone business.
As for Uncharted, just know that they lost key people, including the woman that was the 'showrunner', if you will, for the franchise. I'm sure Uncharted 4 will look great, but folks weren't just into that series for eyecandy.
And I do like Nintendo's discussion that both 2D and 3D Metroid titles are in development. Something tells me Nintendo will have tricks up their sleeve for Gamescom later on...
