Anyway, Gamespot also ran news on the rumor. They actually mention the link I linked on this thread and said:

"An Ensemble Studios poster on the official Halo Wars forums didn't specifically deny that the high-profile real-time strategy spin-off of Microsoft's sci-fi cash cow was canceled. However, he did post a picture of a man in a tinfoil hat in the thread on the subject, showing exactly what was thought of the suggestion."

Still think I shouldn't have posted this dud?
