The AMD rumor makes it seem like the device, whatever it may be, will only be announced/unveiled in 2016, not released.
That said, if it releases in 2017 I'd consider it a 9th gen system. Dreamcast released 2 years prior to PS2 and was also included among the 6th gen systems because it was the successor to the Sega Saturn.
