Best of the three platform holder E3 conferences by far. Reggie is just a great presenter, and he had a good script, too. No awkward "Thanks, Reg-dawg!" *backpat* *armhump*/"Thanks you guys, such amazing work from you there, good stuff, really!" handoffs. No overstated excitement. Just a low-key, concise show of content. I approve.
The Zelda showing was embarrassing of course, but I had already decided to not play another motion-controlled Zelda, and for exactly the reasons that were evident there. So for me that's not even a loss. I just hope they learn something from it, eventually.
Everything else was great.
I think there's some weird platform convergence in our near future. I can see the 3DS gaining tons of games (ported or otherwise) that would previously be exclusive to the PSP, due to the new analog nub. Conversely, the PS3 may see an influx of former incidental Wii exclusives ported to a Move control scheme, e.g. stuff like Silent Hill and the rail shooters -- Dead Space Extraction is already confirmed.
