They showed off several models, including a super cheap 6" model which lacked a touchscreen or frontllight but had a retail cost of only $43. The unit on display, curiously enough, had a Bebook logo (I thought that company was out of the market). And as we can see in the background Yitoa has a number of different models in display.
But more importantly, Charbax also caught a couple new 6" models, one with a Rockchip CPU and the other with an Allwinner CPU. Both of those ereaders sport a frontlight and touchscreen, and they also run (or can run) Android 4.0.
I can't tell if they also come with Google Play, but I would not be surprised to find out that they do. But I can add that the one model is running on a 600MHz Rockchip RK2818 CPU with 4GB internal storage, a capacitive touchscreen, and a frontlight - but no page turn buttons, alas.
I checked and neither of the new models is shown on the Yitoa website, so unfortunately I can't provide more info.
I have to admit that I was surprised when this video crossed my desk today; like everyone else I had thought that the ereader market was dying out, and yet here was a Chinese OEM investing in developing new models.
Either development costs are lower than I expected, or the ereader market (even in its depressed state) is still large enough that sinking the development costs is worth the risk.
