NVIDIA obviously isn't doing much talking about it itself just yet, but Fudzilla
apparently has it on good authority that the company is indeed already hard at work on Ion 2, which promises to bring with it plenty of improvements over the already impressive Ion
chipset. Chief among those is a decreased die size, "much faster graphics," and more than twice the shaders of the original Geforce 9400M /MCP79 chipset that the current Ion is based on (which uses 16 shaders). Not many more details than that, unfortunately, but NVIDIA is supposedly looking to launch Ion 2 by the end of this year -- although not before it sells plenty more Ion 1s, of course.
