What am I NOT getting in Halo 4?

Hear me out, I REALLY wanted to get the limited edition of Halo 4, but its out of stock/preorder everywhere!

It also sounds like they’re is a lot of in game benefits for getting this version, which is really -Yoink!- me off, mainly these six customizations and emblem etc.

Most websites have scattered information comparing the regular to limited edition.
Can someone tell me what I’m NOT getting? I’m really bummed and just wanted to know if its really not a big deal.
