The outfit was expected to unveil a host of new products at the event – not least the HTC One M9 Plus, the HTC One E9, and the HTC One E9 Plus.
However the new slate will use an 8.9-inch display with a 1530 x 2048 pixel resolution nd powered by a 2.2GHz octa-core Allwinner H8 processor, built using a 28nm manufacturing process.
Graphics, meanwhile, will be handled by a PowerVR SGX544 GPU. It will have 2GB of RAM and two storage options – 16GB or 32GB.
Other purported specs include a 16-megapixel front-facing camera, an 8-megapixel rear-facing camera, a 6,700mAh battery, and a chassis measuring 7.88m thin. It will feature HTC's BoomSound stereo speakers.
The OS will be Google's Android 5.0 Lollipop operating system, skinned with HTC's Sense 7.
Last month, there was a suggestion that HTC was working on a new tablet that would be based on the Nexus 9.
In the end the Nexus 9 was, of course, built by HTC for Google, and used a 9-inch display so that rumour was probably about that.
HTC hasn't had the best record with tablets so far. The Nexus 9 was met with lukewarm critical reception, while its HTC Flyer and HTC Jetstream flopped.
