Here are a set of clean images from the upcoming Prince of Persia line. Click through for the flickr page where you can view the super hi-res images by clicking on the "All Sizes" button above each photo. 7572 Quest Against Time was not included in this batch. The series is set to be released in April. Oh hey, that's next month. If I were a betting man, I'd guess Toys'R'Us stores would be the first places you'd be able to find these sets. Just be aware of any possible markup over MSRP before you pull the trigger there.
P.S. I have no idea what happened to the Desert Ambush picture. It's been upscaled horribly.
