Gotta agree with most of Kieron's post, there. I watched half of the pressers live, and most of the others later - I think the only one I skipped was Nintendo's.
Microsoft's was great, and when you consider they've got so much good stuff happening they've deliberately delayed several games into early next year* it's all the more impressive.
I checked my xbox One last night (bearing in mind I'm in the preview program so get some stuff early) and there were about 8 xbox 360 games ready for me to download and install on my One. I downloaded Super Meat Boy, but didn't get a chance to play it. Others there, waiting for me to download, included Perfect Dark, one of the Kefflings games, and Defense Grid.
I also downloaded Fifa 15 and Battlefield 4, to hopefully have a quick blast on while they're free.
The Elite Controller looks fantastic. Shame about the price, though. $150/£130 is a lot of money. A couple of websites had it mispriced at £40ish yesterday, and I gave it a shot, but they both realised the mistakes and cancelled all orders. No harm done - worth a shot.
Most of the games Kieron mentioned look great - I'm looking forward to hopefully playing most of them. I'll confess I've never played a Shenmui game though, so have no idea what that's all about.
(Don't forget Tomb Raider is only timed exclusive, K, rather than a full exclusive. I'd imagine it'll hit pc & ps4 around Feb 2016.)
As for Nintendo, I truly hope they had a bad one because they're hard at work making games for the NX. They need to get it right this time. With the U they brought out an underpowered machine and had no real big games for the first couple of years. If the NX has a decent amount of grunt and has a good lineup at launch and in it's first year then it should be a winner - especially if it comes fairly soon. (A lot of assumptions there. Have they actually officially announced the NX, or that it's a full console yet?)
All things considered, that was one of the best E3's we've seen in the last decade, imo (though of course all the big news about the two new consoles a couple of years ago was the biggest). Very enjoyable, and I'm hyped for several games and developments

I'm taking them at face value, there. It's possible there have been unexpected delays on one or two of the games, but I genuinely think they've held back Crackdown, Quantic Dream, and Scalebound because their triple-A release schedule is just too full this Christmas.
