It's gonna be really damn close unless they cut off shipments early. 800K more Wii Us sold lifetime, just about, with about 200K per quarter for MK8 looking like the current trend for the next quarter or two, maybe a tad more in Winter assuming there aren't any fall games, it's entirely possible.
Either way this will probably be the last time we see such a high attach rate on a main console. It's gonna end up over 50% for sure lifetime, possibly close to 60%.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
