Pre-orders and lore

Has anybody caught any of this stuff?

“Peace is shattered when colony worlds are unexpectedly attacked. And when humanity’s greatest hero goes missing, Spartan Locke is tasked with hunting the Master Chief and solving a mystery that threatens the entire galaxy.”

I’m intrigued by this new story information. I wonder why the UNSC links these colony world attacks with John-117. They must link the two. If they didn’t, they wouldn’t send Spartan Locke after him while trying to solve the mystery. Funny enough: This plot is starting to kind of remind me of Mass Effect 2, just based on the small information we’ve gotten so far.
