Amazon listed the Nyko PlayPad Pro for Amazon Fire TV in stock on April 25th. When I check the page now it’s say shipping in 8 to 9 days. You might think it sold out but people who order before that date show they haven’t received anything. So it appears that the shipping date was pushed back 8-9 days. I have emailed Triple Point PR but so far no response.
