I don't think it's damage control, the digital share for QB should definitely be a by higher than normal. Hell it came with all the Alan Wakes & QB Win10.
Not expecting it to be huge difference but I mean hard to say the digital split will fall in line with "normal" splits.
As for the bundle part, I doubt the bundles really took away from many sales. Digital I buy though.
The physical version also came with Alan Wake -- and even beyond the pre-order period, unlike digital -- so I'd be surprised that a W10 version of a game that satisfies that tiny slice of the market that has a capable PC and an Xbox One will have a significant enough impact on sales to change the story much.
But nevertheless, let's say it went from 20% to 30% of the digital share. Even 40%, let's be generous. It changes the magnitude of the bomb, but not the fact that the only Microsoft tentpole release of the whole first half of the year bombed.
