MGS4 preorder?

ok so i have had MGS4 preordered for about a month now, right before they released the info about when it would be released. now i remember them saying that there would be preorder content to go along with it, does anyone have any idea when that will be released, my local gamestop says that nothing has been released and that nothing will be released for it....course i think they are a bunch of idiots but i trust them more then best buy or anyone else.

any info?

Theres mention of this in a thread a couple days ago. People were saying something about a beta being released in April, is that what you mean? Supposedly it will be shipped. I don't know too much about it.
