FUD Zilla heard rumors that NVIDIA is planning to reveal the Tegra 4 SoC (aka Wayne) at CES 2013:
Nvidia will unveil Tegra 4 at CES 2013 followed by more design win unveilings at the Mobile World Congress in February 2013. Tegra 4 is the likely name of Wayne chip that according to Nvidia’s Tegra roadmap is supposed to have ten times the performance of Tegra 2 dual-core and twice the performance of Tegra 3.
Both the graphics core and CPU will be significantly faster than Tegra 3 and the next Tegra in line should get a lot of design wins in 2013. Wayne will be compatible with LTE modems making it easier for US telecoms to launch phones based on next generation Tegra.
