I bought this the day it came out...seem to remember there was a coupon deal or bigger sale w/ purchase of The Lion King. The Blue top will be in blu ray sized packaging, while the orange will have the larger DVD sized packaging. Other than that they should be the same, all depends on if you are as OCD as I am having to have all my blu-rays looking the same.
Great, thanks for the info. Luckily I purchased the blue top a few hours ago for exactly that reason, so the case fits in with my other blu-rays. It didn't actually occure to me that they could be different size cases, but definitely makes sense considering the orange top states DVD + Blu-Ray, whereas the blue top has the blu-ray part first.
