Clever engineering
It's still clearly an early days product, but I'm impressed with the level of smart that went into this. It may need to step up with a wider field of view, etc., but it's actually genuinely original R&D that seems to be heading for the market. XBox was once doubted, Nintendo was streets ahead, so Microsoft can do this if they stock at it, don't encumber the licences too much, and get a little bit lucky with the launch and press response.
