Packed inside the upcoming iOS 5.1 are 4 new wallpapers specifically designed for the iPad. The fine folks over at 9to5 Mac discovered these new wallpapers inside a copy of iOS 5.1 beta. Your choices are two ocean wallpapers, a grassy dew one, and a puddle with raindrops. Although these wallpapers have a 1024×1024 resolution (for both iPad landscape and portrait modes), 9to5 Mac has also sized them down to retina resolutions for the iPhone 4 and 4S.

Due to the fact that these wallpapers only came with the iPad version of iOS 5.1 beta (and not the iPhone version), there has been speculation that these new wallpapers will officially be released hand-in-hand with the new iPad 3. However, it’s also worth noting that these wallpapers don’t have a higher resolution as many are speculating the new iPad 3 will have. From the 9to5 Mac article:

Something interesting to note: Apple shipped an all-new wallpaper set with the iPhone 4. The iPhone 4 was the first iPhone to include a new screen resolution, so Apple needed to make new wallpapers of the Retina size. Apple could be doing the same with the iPad, but we’ll have to wait and see. To clarify, these downloads aren’t for a Retina iPad.

Who knows? I think it’s a bit early to start rumors based solely off wallpapers inside an iOS beta, but people are always trying to decipher Apple’s secrets before release dates. You can download both iPad and iPhone versions of the wallpapers below, or (if you’re greedy) you can download a .zip of all the wallpapers.
