the roadmap, everything was a year earlier than we're seeing now. The old roadmap had Kal-el (Tegra 3) coming in 2011, and Wayne (Tegra 4) in 2012, but that obviously hasn't happened. The new roadmap has Logan (Tegra 5) coming next year, and Parker (previously Stark) coming in 2015. Parker is said to be 100x faster than the Tegra 2.
NVIDIA also gave a bit of info on the GPU upgrades, which currently use the "Kepler" core. Logan should feature the "Maxwell" GPU core, and Parker will feature "Volta", which will move to 3D transistors and stacked memory for better performance.
