iPad 2 Screen Thinner, Anti-Reflective, 1.2GHz Dual Core CPU?

Oh, I doubt they would have updated (or they'd have used a better GPU) if the SGX535 couldn't handle everything at 960x640 and 1024x768, they would've thoroughly checked it, benchmarked it, tested it, to make sure it can handle it.

There's always a limit to the workload hardware can handle. I doubt Apple would have done performance testing for every app in the App Store, let alone modifying every OpenGL ES app to check how it runs at 960x640 without even having the source.

I just can't see it happening, that is, Apple, using a GPU which will consume about twice the power of the previous to get 4x performance rather than just 2x.

Despite what some might say, Apple do have competition. And they identified games as one of the main attractions of iOS devices.

Then there's OpenCL. And it wouldn't consume twice the power processing the same workload.

Na, but they could have easily found the most intensive game or one close to it, or perhaps even written their own app to test what the limits of it, and what developers are currently capable of producing, etc.

I imagine the CPU is a bottleneck on the 3GS, etc., and prevents games from fully utilising the GPU, but with the 4 and it's much greater CPU it can be utilised more, which seems to comfortably handle games at that higher resolution.

That's true on both points, I do hope they use the SGX543MP2 and can find a way to produce 4x that performance on iPad 3 for a retina display.

If you're playing a game, I.E, Infinity Blade, it'll use both GPUs (twice the power) and simply produce a higher FPS, would it not? It wouldn't finish quicker, since the game isn't a task, it ends when you quit.

It's not that simple. Developers could easily take assets from another platform that would really stress the GPU. The CPU isn't the bottleneck if you just throw complex geometry and shaders at the GPU.

I should have clarified. If the framerate is low on the current iPad then yes, you'd see a higher framerate and potentially higher power draw (though SGX543 is likely more efficient per frame). But while peak power draw could be higher the framerate is capped at 60 fps on iOS devices, so less demanding games should use less power than on the current iPad.

i think my guess was right.

From what I get, the iPod Touch's camera is the same as the iPhone 3GS's camera, which I like very much, so if it's the same camera on the iPad2, it'll be a good camera.

You are mistaken. The 3GS has a 3.2MP autofocus camera with a decently-sized sensor (for a phone). The iPod Touch has a 0.7MP fixed-focus camera with a minuscule sensor that is only marginally useful for video--photography of any kind is more or less out of the question. Thus far, it appears the iPad is likely to have a camera that is either the same or very similar to the crappy one in the iPod Touch.

Wouldn't it be better to have more than 512MB of RAM... so that it's actually better than an iPhone? I don't know if you could ever need more than 512MB.. but couldn't some apps be optimized for more RAM?

It would be better, and offer a longer useful lifetime. But 512MB is certainly good enough for 2011, so I suspect that's what Apple will do. That gives 300+ MB of memory for programs, which is sufficient for any currently available apps, and should be enough for those coming in the immediate future.

We'd all love to see 1GB, but it just isn't likely. Apple wants you to buy an iPad 3, after all, and they certainly aren't above crippling the 2 in the long term to make that happen (as they did with the 1).

Of a dual-mode e-paper screen? How so? Unless I have missed some info the last I heard was that the consensus was that Apple wouldn't change the screen in iPad 2 - more likely iPad 3.

i think you probably misunderstood, it said Ipad would have the same res, not the same screen, in my link the woman even hints she's working on a special screen just for Apple, read my post for the link and keywords.
