The positional tracking tech valve is using seems like the most elegant, robust solution I've seen yet, so I certainly hope it becomes a standard. The best part about it is that the cost per device is so low to implement it (the tracking components on the objects are dead simple and very cheap to make) so there's a good case to be made for using this standard, because you could proliferate all sorts of low cost tracking controllers to use with it.
