Because it has different release date for different parts of the world lol... check out information on internet before asking strange questions:
NA May 15, 2012
EU June 1, 2012
AU June 7, 2012
I did check, and got very different info from what is talked about here.
I got NA released already through Atlus for 50$ (including DLC and Prima Guide), and possibly everyone else on June 1/2. (the one on Steam)
And the Focus version for 35-39$ (the one on Gamersgate) that is released only on June 7th.
However, people here are talking of having the Focus version with the Atlus NA date despite not even being Americans.
