You have to realize that the game takes place in new monbassa, which is near a major flood infection during halo 3, bungie also says the game grew exponentially, master chief wasn't gone from earth all that long so there is a slight though unlikely chance that you may see flood during the ODST campaign, Though I doubt that the campaign lasts all through halo 2's and the beginning of halo 3's campaigns.
Also a multi-player experience dose not have to adhere to game canon, so there could be flood as a bonus level for firefight but again it is unlikely.
