If Wii Sports Resort has the same attach ratio worldwide as Wii Sports has in Japan - 46%
If extra WM+ attachments have the same attach ratio as Wii Play has worldwide - 42%
If the Wii install base is around 80M, a year after Motion Plus is released.
Thats 36M people playing Wii Sports Resort plus another 15M buying extra attachments in the first year.
50 Million units in its first year????
Even if we take the extreme low end. Assume the install base is 50M in Q2 2010 and WSR has an attach of 20% with 20% of those sales leading to another attachment being purchased. Thats still 12M.
Taking into account that the WM+ HW will be a lot cheaper than the balance board. It will be bundled with the sequel to what will soon be the best selling game of all time. More than one WM+ will be sold per copy of WSR. I think we may be looking at the most wanted item of 2009 and 2010.
Now lets get really scary. Imagine if WM+ becomes the standard. Imagine if Nintendo unbundle Wii Sports and bundle WS Resort instead. With a bundled WSR selling the system for the next 3 or 5 years instead of Wii Sports, we might just have found the WII SPORTS KILLER and WM+ could OUTSELL THE WII.
