I just found out that in issue 211 of Edge magazine it states that Bungie has a team of developers working in Valve's headquarters on a secret project.  What could that possibly mean?  If this is true it certainly raises alot of questions especially with the recent trademark Bungie made for Bungie Aerospace.  Could Valve be leaving behind their Source engine soon and instead start using the rumored new Bungie middleware engine?  Just curious what your guys theories are cause thats pretty crazy stuff.

Left 4 Halo: Portal to Marathon

Bungie + Valve = Sold (whatever game it is is sold to me, I mean)
Bungie + Valve = orgasm
Bungie + Valve = endless fun
Bungie + Valve = best story ever!
Bungie + Vavle = best gameplay ever!

And I could go on forever.

Balve?

OT: Hmm, I don't know. I really like the unique look of the Source engine. It has a ton of personality even though it's not teh l33t haxxorz uber graphixes!

Halo-Life hehe.

I don't know how much of this would be true. But I love Valve and this seems very interesting if it does end up being true.
