There's a difference between having the most impressive presentation and presenting what YOU want to see.

Having the most impressive presentation = winning.

Presenting what you want to see = pleasing the fans.

Without a shadow of a doubt, Nintendo is going to win this time. Cafe alone will beat anything else that's presented. On top of that, we're going to see Nintendo's future plans for 3DS, their final hard-hitters for the Wii, and I'm certain there will still be something good for the DS.

Sony has Uncharted 3 and the NGP. But, the NGP can't do anything new that the 3DS isn't already doing, so it's entirely based on what library they present. Given that the PSP never had anything THAT impressive along the lines of exclusives, it'd have to be either handheld varieties of home console IPs, or new IPs, and neither of those commands much excitement. I loved my PSP, but it never had anything worth THAT much excitement. The PS3 is just now being maxed out in what it can do, so they MIGHT have something impressive to bring to the table that they didn't have before, but so long as it's just games along the same lines as what they've already been doing and nothing specifically NEW, they won't be able to do anything incredible.

Microsoft, their hard-hitters strike very differently than Sony's. They appeal to a much broader audience than Sony's, but still mostly to the same people as well. I expect that they'll have a better home console presentation, but without a major presentation like the NGP, they won't stand a chance to beat them in the overall grand scheme of things.

Third parties are a big decider in this race too, though. Good third-party support can make or break the whole situation. If all third-parties announced amazing new titles for the 360, then regardless of what Sony and Nintendo have up their sleeves personally, M$ could still walk away the "winner".

But as for their own individual presentations, Nintendo will have it hands-down, and there's absolutely no arguing that objectively.

Please, leave your subjective fan-related arguments behind here. You're arguing your personal opinion about these things. I am not. I own and play PSP and DS. My most enjoyed systems across each generation vary across the board. I am an unbiased gamer here; you are clearly arguing personal bias.

At such a small screen-size, there's not much you can do with greater graphical capabilities. Take a screenshot from God of War 2 and a similar screenshot from God of War 3. Side-by-side, at full resolution, you can obviously tell the difference between the two. But shrink it down to handheld dimensions and it's an entirely different situation. The NGP's power won't be that noticeably better than the 3DS, unlike last generation. There WILL be a noticeable difference - don't get me wrong - but it'll be insignificant enough that generalizations can be made.

And while the controller setup IS better for FPSers, that doesn't change the fact that the 3DS still can do them fully. And the analog touchscreen setup DOES have advantages over dual analog (though I personally do prefer dual analog).

No, the NGP does not have a touchscreen on the front and back. It has a touchscreen on the front, and a touchPAD on the back. And that isn't going to offer many advantages, either.

Gaming-wise, no, it really can't. It has things it may be able to do a bit better, but there are absolutely zero functions it has above the 3DS. And when talking a gaming conference, with everybody touting their gaming features, that's a tad important.

Really, guy?

-dual-screen gameplay
-3D display
-backwards compatibility

then, if we want to list things it does better too:
-widescale affordability
-pocket-sized portable handheld gaming
