Well last time I heard anything, Infinity Ward got fired because of non-obedience. So just like Halo lost Bungie, they also lots a whole shit load of fans, brownie=points, and series of games. Once Halo lost Bungie and tried to make ODST, everything fell through the shitter. Which equals CoD losing Infinity Ward, they just basically fucked themselves over and Black Ops won't be as great as suspected. And yes there is a Zombie type Horde for it.
Dude, there's nothing right with your post.
As someone already said, IW never had anything to do with Black Ops. Activision has had IW and TreyArch on alternating development cycles for CoD for the past few years. IW made CoD2, TA made CoD3 (didn't have 2 years though), IW made CoD4MW, TA made CoDWaW, IW made CoDMW2 and now TA is making CoDBO.
Also, Bungie is still on Halo, through Halo: Reach. They made ODST, it was just a smaller team that worked on it, while the majority of the studio was working on Reach.
The only thing that may be right with your post is the Zombie mode, which was in WaW, because TREYARCH (not IW) made it.
