It will be something crap just like all the others, first was a poster and 2x XP for MW3, then went better with Nuketown 2025 but then they announced you get that with hardened and care package edition. I can't remember the 3rd wave, but wouldn't have been better than Nuketown! So my guess is could be like 1-2 extra unlock tokens when you reach level 4, but then that will mess up there token strategy!
