ViewSonic introduced not only a Retina Display handset, but also a 7 inch Android slate and 10 incher Windows and Android models. Now it appears that the company has 3 more slates coming up. Engadget is saying that ViewSonic will unveil at MWC 2012 a 7 inch tablet, a 9.7 inch one and a 10 inch unit.

The 7 inch one is the ViewSonic ViewPad G70, that we already knew about. This one comes with a 1024 x 600 pixel resolution, 1GB of RAM and 4GB of storage, plus Android 4.0 Ice Cream Sandwich. Next up there’s the 9.7 inch ViewPad E100, with a 1GHz processor, a 1024 x 768 pixel display and Android 4.0 once more. This device measures less than 0.4 inches in thickness and should weigh around 1.4 pounds There’s also the ViewSonic ViewPad P100, with a 10 inch 1280 x 800 pixel display, a 1.6GHz Intel Atom N2600 Cedar Trail CPU and Windows 7 as the OS.

From the sound of things, the ViewPad E100 is actually an updated Chinese ViewPad 97a and the ViewPad P100 is actually a modified ViewPad 10pi with the new CPU replacing the slower Oak Trail unit. Starting from tomorrow we’ll also be providing quality hands on videos straight from Barcelona.
