Seriously, you guys are talking past each other, rather than to each other.
TheLastStarFighter is operating on the idea that system sales and game sales will mirror each other - a plausible idea.
Troll_Whisperer, etc, are operating on the idea that system sales increase and game sales will mirror each other - also a plausible idea.
Until we have hardware data (at least for the UK), the speculation is entirely pointless.
EDIT: For anyone confused as to why TheLastStarFighter's version is plausible, try turning the logic on its head - it's not that the sales of Mario Kart 8 are what are increasing Wii U sales numbers, it's the other way around - people are buying Mario Kart 8 alongside their Wii U. Similarly with Watch_Dogs and PS4.
