Google I/O 2015 tipped to be another send-off point for Google Cardboard, the company's virtual reality pre-brand. The stars are aligned. It's time for Google to treat Cardboard - and the virtual reality community in general - like the sleeping tiger it really is. This week at Google I/O 2015, Google is likely to reveal far more than they did last year, when the VR headset Google Cardboard was given away with barely a word on what it was capable of doing. This platform is about to blow open.
