All Tegra 2 Motorola devices "Will Remain on 2.3 Gingerbread"
I'm an Atrix developer and I find this appalling. Just what the hell does Motorola's software development team do?
Notable exceptions to this are the Xoom tablet. The Verizon version is still on ICS. The Google WiFi version has been on Jellybean since July, though they're both still on a 2.6.x kernel.
If anything, I think this failure should be shared between Motorola and NVIDIA.
