Last week we confirmed NVIDIA would be introducing a Tegra SoC with integrated Icera baseband called Grey, but we got the timeframe down. Above you'll see the updated Tegra roadmap. Wayne has been pushed out to late 2012/early 2013 and there's now a Kal-El+ part that will refresh the lineup in the middle of next year. Grey will debut in 2013.
Also note that with Wayne, NVIDIA bifurcates the Tegra roadmap into a high end and a mainstream SoC. Wayne (and its derivatives) will continue to be two chip solutions with a discrete modem, while Grey will introduce single chip solutions with integrated Icera basebands.
