It looks like our schedules have just become a bit more cluttered: following Nokia, Microsoft, Motorola, and now Apple, HTC has just invited us to an event on September 19th in New York City at 11AM EST. There isn't much to tell from the invite other than a slightly "Metro"-looking logo at the bottom, but we've been hearing rumors for a while now that HTC is gearing up for some Windows 8 devices. According to those rumors, which pointed to an event in the third week of September, the devices will be available in November. We've previously detailed the company's first expected Windows Phone 8 devices — the flagship "Zenith," midrange "Accord," and entry-level "Rio," but it's possible that we may say that rumored 5-inch Android phone, too. Whatever HTC has to show us, you know we'll be there to cover it live come 11AM EST on September 19th to see if HTC can best whatever Nokia and Microsoft have to show us tomorrow.

Update: Added detail on rumored Android device.
