Nvidia's Kal-El, aka Tegra 3, should be available by the end of the year, integrating a quad-core Cortex A9, efficiency enhancements, the ability to decode 1080P full bitrate h.264 Blu-ray quality videos, and an improved 3D capable GPU. Anandtech just published a very interesting article about it if anyone's interested...

What's amazing is that functioning silicon was demonstrated live, and it actually performed as claimed. 1440p 50Mbps h.264 stream decode, and output to two displays simultaneously, as well as processing performance similar to a Core 2 Duo T7200. I'm honestly speechless. The only unknown is power consumption, but if Nvidia is to be believed then given similar workloads it should fit into a similar power envelope as the Tegra 2.
