Are hackers expected to be in Black Ops?

Will they own the top 400,000 spots on the leaderboards of Black Ops, as they do on MW2?

Are Treyarch working on something to try and "fix" the hacking epidemic?

I really hope they do. Hackers on MW2 have wrecked the game. One of my favorite parts of the CoD series is the competitiveness - the first to tenth prestige, but ofcourse, if hackers are going to be on the game then there will be none of this mega hype about who will top the leaderboards. That will wreck the game for me.

the game will be a failure if there are hackers.
