Does anyone know what it was?
The only thing I’ve heard from SDCC is that they tried launching SA today.
I think it’s referring to the new Halo comic series. I can’t say for 100%, but I’m pretty sure.
It was the tablet give away!! 
wasnt a good suprise though… expected better
It was the Surface Giver-way…
Would of been nice of 343 to of just not added in saying with a MEGA surprise.
People thoughts would of been Halo Xbox One info, Halo TV series info etc…
