I have pre-ordered Black Ops for the Xbox360 Looks sick as fuck.
It will have a currency system like Counter Strike, you can also customize your player appearance and a lot of other things. There's a new game type called Wager Match where you can sort of gamble with your money, the top 3 winners of the match wins all cash from the losers. Check out the videos, they're pretty cool. A new killstreak reward lets you control an RC car bomb. =)
