Taiwan-based HTC is following in Apple's footsteps and has sent out invites to its press conference, scheduled for Sept. 19 in New York City.

The invite does not divulge much but teases with its "save the date" and "join HTC to see what's next" phrases. The press event is slated to kick off at 11:00 a.m. EST.

"A graphic of some sort appears at the bottom of the invite, but it's hard to say if it actually has anything to do with what we will be shown off or if it merely is filling out space on an otherwise bland invitation," stated a Phandroid report.

HTC's invite may not provide too many clues, but expectations are that the Taiwanese smartphone maker will announce a gamut of smartphones, including its first Windows Phone 8 smartphone, dubbed the Accord. The other rumored devices include the Rio and Zenith smartphones, which are also allegedly based on Microsoft's Windows Phone 8 OS.

Rumors indicate that the mid-range 4.3-inch Super LCD 2 display Accord will feature a 1.5GHz dual-core Snapdragon S4 processor with 1GB of RAM. The NFC-enabled smartphone will likely sport an 8-megapixel rear-facing camera.

The Rio will reportedly feature a 4-inch WVGA display and a Qualcomm MSM8227 processor. It will sport a 5-megapixel. On the other hand, the high-end Zenith is expected to have a 4.7-inch Super LCD 2 display , a quad-core Snapdragon processor, and will likely feature a 8-megapixel rear-facing camera. The Rio and Accord Windows Phone 8 smartphones are rumored to launch in October, and the Zenith could possibly see a Q4 2012 release.

Samsung revealed the world's first Windows Phone 8 smartphone, the ATIV S, last week, and Nokia and Microsoft are set to unveil their Windows Phone 8 smartphones at a joint press event today (Sept. 5). The HTC announcement could further boost the Windows Phone 8 platform.

Tech gurus predict that HTC could also launch its mystery 5-inch device, said to be Samsung's Note 2 phablet's challenger, at the Sept. 19 event.
