"The next time you see me, I'll be stabbing you to death! Okay?"
The Flood doesn't fit in with the time period in which ODST takes place. So as many have said, no flood will be present in ODST.

There should be Flood in ODST Fire Fight at least, cause Sgt. Johnson was not in that city after Chief left, cause he went with him, yet Johnson is usable in Fire Fight, but yet no Flood to fight, what gives? (You don't believe, play Halo 2 again and you'll see what I mean)
As For Sgt. Johnson, he's only available if you get the special addition, and only for Firefight. Firefight isn't the campaign mode. That's like saying that the entire time Master Chief was on Halo there were a bunch of other Spartans and Elites playing Capture the Flag.
