The internet and wild speculation are like peanut butter and chocolate; they just go together. Today's wild speculation began when I ran across this entry on Phuze (which actually looks like a cool ezine). The speculations goes a little something ... a-like-a this: Bungie reported in their most recent update that there was a special "BIG" Halo announcement coming this week, in celebration of Halo's fifth anniversary on Wednesday, November 15th. 1UP's Halo 3 page lists a "Special Halo Announcement" as part of tomorrow's coverage. Phuze speculates that this announcement is probably something along the lines of an official release date -- and we agree -- but proffers the tantalizing possibility of something more. What if, wonder of wonders, it's an actual playable Halo 3 demo? Is it possible? Very slightly, yes. After all, as Phuze notes, all these game journos were playing a multiplayer build as early as last month, so it's possible (not to mention it's a great way to make 360 owners forget about the PS3).

Allow us to add even more fuel to the fire. Tomorrow, as most of you are no doubt aware, is Wednesday. Wednesday typically marks the release of a new Xbox Live Arcade title. Could Bungie have an Xbox Live Arcade title lined up for the anniversary of Halo? If they do, what better way to celebrate Halo's birthday than by releasing its spiritual prequel, Marathon? So there you have it. If Bungie releases Marathon on XBLA tomorrow, you heard it here first. If they don't ... well then why the hell were you listening to us in the first place?
