The A511 is supposed to be packing in both WiFi and 3G connectivity. There is a model called the A510 tipped as well sharing the same hardware, but having WiFi only. There is no indication of what OS the tablets will use. It would make sense that they will get Android 4.0, but that isn’t noted in the source code.
Another thing we don’t know about the tablets is when they will hit stores. Many of the markers of Android tablets are rushing to get the Android 4.0 offerings on the market early so they are available well ahead of Windows 8 tablets expected in Q3 2012. We may see these tablets for the first time at CES in January.
