got this info from wiki read and wonder indead....
Blizzard announced in March 2006 that the game is on "indefinite hold" while the company investigated seventh generation video game console possibilities. Subsequent public statements from company personnel have been contradictory about whether production will be renewed or planned story elements will be worked into other products. The continued delay of Ghost has caused it to be labeled as vaporware, and it was ranked fifth in Wired News' annual Vaporware Awards in 2005. Although Blizzard Entertainment refuses to list it as such, video game journalism outlets including IGN and GameSpot list Ghost as canceled.
