According to Jack Tong, HTC's president of North Asia, the Nexus 9 represents HTC's commitment to returning to the tablet market after having abandoned it for three years. That's significant because, well, the tablet hasn't been officially acknowledged or mentioned by almost anyone outside of NVIDIA through legal documents. Focus Taiwan is reporting the news, suggesting that Tong announced the company's plans for the tablet at a press briefing in New York.
Tong did not mention anything else from what we can tell, but Focus Taiwan mentions a potential launch date of October 16, which is next Thursday.
The tablet recently cruised through the FCC, so it would shock us to see the tablet arrive within the next couple of weeks. Keep in mind that we should also see Android L at that time as well.
