Anecdotal of course, but I've seen a number of kids in my area with Switches of their own. Obviously that demographic will explode oncd the Switch drops to the sub-$200 range, but I definitelty feel price isn't as much a deterrent for some parents as most believe.Now they need to try and get the device in handheld pricing area so typical handheld players can join.
Personally I consider the Switch hardly more pricier than the original 3DS, and its by far the better bang for your buck. You don't even have to focus on the home console functionality either - just knowing that for $50 more and a half-hour/hour decrease in battery life, I get a device with far better graphics, build quality, and support makes the Switch worth its price tag.
