The aging HTC Touch is soon to be replaced by a new . The Opal was revealed by what seems to be a leaked internal HTC document, and informs the new handset will feature HTC’s latest TouchFLO 3D touch user interface for its Windows Mobile 6.1 operating system. Taking obvious design cues from both the Touch and Diamond, the Opal will share the same TI OMAP 200MHz processor of the original Touch under its skin.

Onboard memory will consist of 256MB and RAM will be fixed at 128MB. The same 2.8-inch, 240×320 pixel touchscreen of the Touch will do duty in the quad-band device. Other Touch carryovers will include the 802.11b/g Wi-Fi module, microSD card slot, 2.0-megapixel camera and Bluetooth 2.0 short-range wireless device connectivity. Most popular digital music formats will be supported; extra Internet support is also likely through Opera’s web browser as well as support for RSS news feeds and podcasts.

The Opal will be available in a few colors, though they are not yet known. Pricing and release dates are likewise not specified and aren’t expected to show until closer to an official announcement.
