After having made a big hit since it released the the ASUS Eee Pad Transformer, Asustek Computer now has its eyes set on a next-generation upgrade to the Eee Pad Transformer.

DIGITIMES reports that ASUS will load its upcoming tablet (which we shall refer to as the “ASUS Eee Pad Transformer 2” for now, for lack of an official name) with the quad-core NVIDIA Tegra 3 processor and the unifying version of the Android operating system–Android 4.0 Ice Cream Sandwich.

The release date for the ASUS Eee Pad Transformer 2 has not yet been specified, but sources say that it may come out in the fourth quarter, most likely in October at the earliest.

ASUS hit big sales in the first half of this year by shipping over 400 thousand units of the entry-level ASUS Eee Pad Transformer. Sources say the success of the Eee Pad Transformer spurred further demand for the tablet. ASUS plans to ride high on that demand wave.

DIGITIMES sources say that, although the ASUS Eee Pad Transformer ships with “above-standard components,” its US$400 price is just about break even with the device’s production cost. ASUS’s profit engine is the separately sold keyboard docking station for the Eee Pad Transformer, which most customers buy along with the Transformer anyway, as it extends the device’s functionalities.

You can expect the Transformer 2 to be compatible with the keyboard docking station of the current Transformer. The price will most likely be around the same point as the Transformer. But, unlike the Transformer, the Transformer 2 just might be slimmer, lighter, and faster–just as ASUS promised. Do you want to wait out a bit for this one?
