We were shocked how well it coped so far outside its intended use! It's a brilliant bit of hardware, definitely a strong competitor for the Oculus Go and we hope it sees a worldwide release in the not too distant future. Until then, we're looking into reselling and shipping the Focus from the UK, if you're interested, let us know in the following Google form:

It's designed to bring the VR experience to the average home, educational or training users, who don't have the gaming PC, the space or the money for PC VR. Standalone is better for media viewing, experiences and puzzle games, only worse for complex 3D gaming. But it's really up to developers to work within its limitations and build awesome VR experiences!
We're still not sure about the Santa Cruz either. As far as we can tell, it'll be using a custom smartphone chipset, unlikely to be much more powerful than the Focus or Go. Even if they wanted to use more powerful hardware, they'd then have to tackle the power requirements, so it seems unlikely there is another option. The release still seems to be a long way off (Q4 2018 at best), so it's not really meant to compete with the Focus anyway.
