Motorola appears to be brewing up the successor to the Xoom Tablet which could be called Motorola "Kore", the "K" version of "Core". According to news reports from Android Authority, the upcoming Motorola "Kore" is expected to be released with a non-widescreen aspect ratio of 4:3 to match iPad's aspect ratio.
The upcoming "Kore" from Motorola is expected to run on a quad-core powered Nvidia Tegra 3 processor with 4 "kores" (naturally). This tablet will of course be running on the upcoming Android 2.4/4.0 Ice Cream Sandwich Android OS. The only downside is the aspect ratio in which the current breed of Android Tablets have been running on widescreen aspect ratio and even games have been optimized for widescreen view. It'll be interesting to see if a 4:3 aspect ratio would sell in the Android arena.
