Should I preorder Gears of War 3 for beta code?

I was just wondering what I should do as far as trying to get into the GOW 3 beta, the problem for me is there is currently no information about a special/limited edition. I really really really want to get into the beta but I want the special/ limited edition and Epic isn't providing any info as to this situation. Also I don't have any interest in Bulletstorm so that's out. Info please?
