My rationale is that while it's true that families have multiple TVs today, the game console is probably hooked to the big one. They're marketing consoles to families now, not just as something to stick in a kid's room. The parents probably use the console for Netflix and play it themselves occasionally, but the kids are going to want to play Pokemon all night. Most people aren't going to move a console between TVs all the time to reclaim their main screen. For Nintendo's target crowd, I really like this idea.
