I think it will be in the tactical combat module they've mentioned.
I don't know what ToB style maneuvers are, but I'm sure there will be some sort of robust tactical options for warrior classes in the "Standard" rulebook. Whether that'll be part of the initial release is another story.
I don't really want a robust tactical maneuver system though. I just want maneuvers that provide certain martial warriors the ability to make interesting decisions on each of their turns.
Oh well, it really seems like people don't understand why having maneuvers would be interesting. 13th age has maneuvers and has no grid at all.
