Maybe it has to do of how it was projected towards it's audience. Maybe they weren't looking for touch screens, maybe they didn't focus on the casuals enough, maybe the console specs made some gamers see that the console was going to be stuck in last-gen. Or maybe not even Nintendo believes in the console, which is not the same that they don't believe in their software. For whom it was geared towards?
