Yes, I'm aware of that. My point is though, everything is going to quadruple in size -- particularly graphics in games.
It's mostly textures that will give issues there, but they didn't have the full 512 to play with before. The OS will use nearly the exact same amount of memory regardless of the screen resolution. (Only the screen buffers will change, and that's not terribly significant. If you actually have 50% of system RAM available to an app on the iPad 2, you'll have 3x the available ram for the same app on the new iPad. So, yes, there might be some extreme cases where the additional RAM isn't 'enough', but they're not going to be common. (Especially since you didn't have 50% of iPad 2 system RAM available *just for textures* in the first place.)

I'm still wondering what the logic is behind called it "The New iPad". What is it going to be next year? "The New New iPad" or "The newer iPad"?
In my opinion they should have gone with "iPad 3" or "iPad 2012".
Edit: wow, disagree with something Apple does and you get a negative rating on your post.
It's not "The New iPad", it's the new "iPad". The only confusing bit is going to be that between this year and next the naming conventions will go:
This Year
iPad (the old, old iPad, newly discontinued)
iPad 2 (the old iPad, now just a base model)
iPad (the new iPad)
Next Year
iPad 2 (the old, old iPad, newly discontinued)
iPad (the old iPad, now just a base model)
iPad (the new iPad)
Beyond that, it'll be just like the MacBook [Pro|Air], iMac, Mac mini, and Mac Pro:
iPad (the old, old iPad, newly discontinued)
iPad (the old iPad, now just a base model)
iPad (the new iPad)
