But this is Japan we are talking about here. DVD players in Japan are not as cheap as DVD players here in the states (unless you factor in the PS2...which...whats the point in adding it to the DC version anyways?). So, it was only availble for the PS2 version (which is not evey buyer of RE:CVX got since, it was only for those who pre-ordered bought the packages, which was like only 1,000).
As for the US version of RE:CVX, unless they decide to package Wesker\'s report seperately, it will not availble for either version.
