Mobile-Review, a Russian tech site, has sent a Tweet that Motorola is busy working on preparing its tablet to run Android 3.0 (Honeycomb). Apparently, Motorola has full blessing and support of Google.
The 7" tablet is rumored to run on NVIDIA Tegra2 processors and have 3G connectivity. Verizon is likely to be the exclusive carrier since they enjoy a strong relationship with Motorola. Note that Motorola is also introducing a 10" Stingray tablet.
