If that's the case, I agree that now his prediction of less than 35M is pretty useless, although not stupid (since it is correct and, I guess, not consensual - I bet there still are some Nintendo die hard fans expecting more than that).
"About" is indeed imprecise. But "less than" is pretty clear. Either the number is lesser or it's not. Where's the imprecision?
Yet, when you say "about 0 units" I know that 0.4 (if it could exist) would be about 0. 1.35 would already be about 1. When a game sells thousands or millions of units, there's no way it can be "about 0 units" (since your scale is in "units", not "billion units"). I think that's logical.
PS: Portugal is the european champion!!! I can't believe it! First title ever!!
It is indeed logical, which is why I say you need to apply common sense to scenarios like this.
