With only two days of sales in that reporting period, I'm more curious to see what kind of bump Pikmin 3 gives it this current week. 20k isn't great, but it's still better than, uh, 8k. I'm not defending it, but it's worth pointing out that 'this week' really means '2 days'.
I want the system to thrive, but it's also bizarre to me seeing people looking towards Pikmin 3 as some sort of system mover. Sure, it'll sell *some* systems, but a lot of those people likely already own a Wii U. Pikmin is one of Nintendo's more niche franchises, anyway. That's the really alarming thing about the Wii U... we've still got months until the *big* titles. I'm guessing that Nintendo is really, really thrilled they have MH4 and Pokemon on the 3DS this fall, since that'll temper at least some of the Wii U damage. Nintendo is going to have a good holiday, but it remains to be seen how much, if anything, the Wii U contributes to that.
The more interesting take-away from the Japanese sales this year is seeing just how much they've basically stopped giving one single about consoles. That's in a general sense, not just Wii U related. I'm really interested to see how the new hardware goes over whenever it launches.
