There's also about ten different topics on the front page about a possible "Halo 4".
To answer your question, there could possibly be a "Halo 4", but that would not likely be the title. In other words, it would be more of a "Spiritual Successor" than a sequel. For instance, there might be a trilogy on Master Chief crash-landing on whatever type of planet/machine that we saw on the Legendary ending of Halo 3, but it would almost definitely have a new name. "Halo 4" just doesn't sound right.
Hope that helped. And before anyone mentions Marathon being the sequel to Halo, it's not. Bungie has confirmed that the Marathon series is set in a completely different universe.
