Doubtful. The first monthly White Dwarf is said to contain stuff about Kharn and some Chaos stuff for 40k. As the White Dwarf would now seem to be a retrospective look on the past month, I think it'd be safe to assume that it'll be a 40k pre order again next week and no significant AoS release until September.
From that, and with the details of the free model on the White Dwarf, it's likely that the first release could actually be the Gorechosen box set too, as the free model isn't in that box (IIRC).
