Over on the Team Fortress site, there are a couple of odd bloodstains on the logo header.
The bottom most stain leads us to what appears to be a birth certificate for three children; Redmond (RED), Blutarch (BLU) and a third child Gray. This is giving the community food for thought as we may find out what is actually going on when we hit 2nd September, the birthday of the three children.
The upper most stain takes us to what appears to the be the last will and testiment of Zepheniah Mann, father of the children. With a story of how they left London in order to explore the new lands, catching every disease going and ending with probably the most interesting statement so far "Lastly to most trusted Elizabeth I leave the entirety of my 'miracle' gravel cache, uncovered with Barnabus during a trip to Terra Austalis. My weakling son Gray resurfaced last year and has threatened to blackmail me for it".
Could it be we're going to get a third team introduced to Team Fortress 2? It would certainly be an interesting twist to the current formula. Or could we see another special event similar to the Horseless Headless Horsemann Halloween shenanigans we're used to.
Only time will tell and as soon as we have more information we will bring it to you
Looking forward to seeing what comes of this in September. It hints in the letter that Red and Blu teams may have to work together - maybe they have to work together to overcome the 3rd son / team Grey?
