Thinking about the Nintendo announcement of the NX (or Switch), perhaps Nintendo knew that the leaks would be all over the Internet after October. It's hard to keep a secret nowadays. Maybe they needed to go forward into production/testing where keeping it a secret would be too hard. Remember how much a secret/not-secret that PS4 slim was. Maybe Nintendo wanted to get ahead of any possible leak.
I look forward to your impressions of it.
ps - REZ Infinity, Thumper and Until Dawn: Rush of Blood are great PSVR experiences. IMHO, they do not justify the hefty price tag, but I strongly urge you to play those on PSVR. Cheapy, see if a CAGer in your area can loan you their PSVR for a week.
