Idk why it would be in game informer magazine already. That decision must've been made a while ago to make it in the magazine. I'm skeptical this is true.
I'd assume these are different teams, and they'd want the data from early tests even if it shows how things are currently borked on larger scale. I'd imagine having their first public Beta a year out from release has to be pretty nice.
Halo 5 is actually being made by 343 and not a bunch of external studios...
I hope they bumped it up because I'm moving around or shortly after dec 29th D:
