Night at the Museum looks awesome

[BluFive]

This is actually a question for anyone who knows.
Since im brand new here does anyone know if night at the museum is coming out on bluray the same day as regular dvd.I read on afew sites and theres no mention of the bluray anywhere,just the standard.Now another question is are bluray movies gonna eventually be released the same day as standard dvds,how long do you think this is gonna take,because some have like click and stranger than fiction {feb 24th},but how long till everything comes out the same day?
