Elitegroup Computer System (ECS), Asustek Computer, and Micro-Star International (MSI) are planning on showing off their latest tablet PCs at CES 2011. We already knew this about Asus, but the ECS and MSI parts are news. In addition to all this, DigiTimes also specifically says that Google will release Android 3.0 in March 2011.

ECS is set to announce 6-, 8- and 9.7-inch e-book reader models, featuring capacitive touch screens, support for Android and Linux, as well as built-in Wi-Fi, Bluetooth, and 3G. The company also hopes to showcase several Windows 7 and Android tablet PCs. Some models will feature 10.1-inch multitouch panels with Intel Atom CPUs, while others will have ARM-based processors from Marvell or Samsung in order to get eight hours of battery life. The company will also display 7-inch models at the show as well as several power-saving 14-inch or 15-inch LED enterprise notebooks with USB 3.0 and ECS' exclusive power saving software Super POSH.

MSI will show off a 10-inch Intel-based tablet PC running Windows as well as engineering samples of its ARM-based model running Android. MSI is also prepared to sell an Nvidia Tegra 2-based model in April or May.
