I dont understand, they released Superman Returns on both formats the same day, but now they only released Poseidon on HD-dvd. There is no mention of a release date for Poseidon on Blu ray so i had to bite the bullet and buy the HD version. This sort of pisses me off, this is a fairly new release, why not put out both versions on the same day. They aren't supporting both formats equally in my mind untill they do (and not 6months to a year later for the blu ray version). Is this some sort of marketing ploy to get people who would prefer the bd verision to double dip?
