By the way, just watched the Switch commercials, and noticed there isn't a single child in any of them. If you still had "doubts" about who is the primary target at launch (and during the first few months), there you go.
I haven't looked elsewhere but presumably it applies everywhere as Amazon JP and COMG! have re-opened reservations for Switch hardware promising day one.
Edit: not everywhere. The My Nintendo Store hasn't re-opened them. Oh, Nintendo!
