The Wii and PS4 aren't really comparable. The Wii burned through a non-sustainable consumer base quickly, one that wasn't really drawn by traditional gaming. The PS4's life's blood is the traditional gamer, some of which jumped over from Xbox. The two don't really intersect to a significant degree.
The only thing I'd like to really know is how many people who got their first taste of gaming with the Wii moved on to the Wii U or jumped to the PS4 or XO.
