Then perhaps Walmart had shortages resulting in NPD overestimating their Wii sales, or something.

This is very possible

It's also possible that Nintndo just wanted to see the internet explode on NPD day.

Like Brett said: wait for Nintendo's financials.

Or they were worried with what NPD would say.  Nintendo has always been a really conservative company. 

Seems unlikely though... a 5% margin of error on 3.8% would be what... 3.61?

Who knows maybe they thought NPD might botch it though and go under 3.5.
