I've Googled around and have been unable to find any answers, and Apple's tech specs for the new iPad don't reveal anything either.
It's a 1536p screen. Can I play that level video, or am I limited to 1080p?

Oh, they're around. Considering they're uploadable to YouTube, one can find them in a variety of places. I wanted it more so to see what it would look like on the screen, rather than for practical reasons, though.Where would you get video at higher resolution than 1080p? (Excepting cinema sources like Red -- I assume that you're not a Hollywood producer)

I downloaded a few 4K video samples from YouTube and I am now re-encoding them to 2048x1536. Some of the 4K video is actually only 1714p (2.39:1 ratio). So I lost less than !!% of the vertical resolution, kept the aspect ratio and cropped around 916 pixels off the sides. The resulting video is 4:3 ratio, but shows almost the full vertical resolution of the original. I'll see if the iPad will play the "normal" profile (as opposed to high profile) 1536p video...
Share your results, i'm interested.

I re-encoded a 4096x2304 (4096x1714 active resolution, without letterbox) video to all different sizes using varying levels of profiles. It seems that the iPad can play only 1080p video or less as long as it is also not any wider than 1920 pixels. I suppose this isn't surprising since 1920x1080 is the Full HD resolution. (It would have been nice if I could do 2560x1080p). This is according to iTunes. (When trying to sync anything larger, iTunes says "video cannot be played on this iPad")
Again, as far as I can tell, iTunes will not sync any video greater than 1920 pixels wide AND 1080 pixels tall.
One more thing to test is if the iPad will actually play wider or taller video by transferring videos by other means than iTunes. Any suggestions on how I can transfer large videos? DropBox, etc?

There are other video players - like OPlayer and FlexPlayer - that might work. I use VLC - but it's no longer available.
I haven't tried using a format larger than 1080p though, let me know if any of these work!
I tried VLC with varying sizes up to 4k, it will play the sound but just throws up a grainy blue image vaguely reminiscent of one frame in the video fo anything over 1080p.
I even tried a 4:3 video at 1920 wide figuring maybe it goes off the width of the video rather than the height, but still no luck.
1920x1080 seems to be your maximum.
1080p is maximum right now. If you try to play 2k video, it will play at a lousy frame rate. The quad core GPU just can't handle it because it's busy trying to push the pixels for the screen. The screen isn't meant to make 2k video available for the iPad, it was meant to display high res graphics so reading and applications would be more vivid.
That's sucks, it's like making a hotel but only having a generator capable of supplying electricity to 1/4 of the rooms.

I can confirm that 2048 footage does play on the new iPad if you get it on there with an App like Goodreader or DropBox. I rendered two clips, one at 2048x1080 and the other at 2048x1280 and they both look amazing.
wouldn't this be more due to the fact that third party app store apps aren't allowed to use the built-in hardware acceleration for H264? AVPlayer HD, for instance is a software player.. and uses the cpus for decoding the video.
We'll know for sure once the jailbreak is released and we can use a third party video solution that does use the hardware acceleration.. like XBMC to do the testing.
Though in reality, most video is going to be 1080p or lower.. so I doubt it will be a concern for most people regardless of the answer.
