"Don't forget about bundles" is a bad caveat for the platform with the biggest install base and I'm tired of hearing it. Ignoring digital sales, it still means that the significantly higher established PS4 install base bought less copies of Uncharted than the lower install base of Wii U bought Wolly World. The same line of defense was up when Destiny was doing better on Xbox One than PS4 at launch and it makes little sense to me.
Certain sales don't count for reasons.
