Their strategy worked out for them last holiday season so it's not a surprise they're going for it again. I do think that QB was at one point rumoured for a Spring release, like Titanfall was last year, but got pushed back. It might be a combination of both development problems and wanting to put all their focus on the holiday season.
Honestly the ideal situation I think would be:
August - Forza 6 Motorsport
September - Halo 5 (It worked well for Destiny and the further away from Call of Duty the better.)
October - Fable Legends
November - Quantum Break
December - Rise of the Tomb Raider
Something similar to that.
