A week ago Engadget managed to get some pictures of LG's dual-core Tegra 2 based phone, here.
The good news is that this phone as well as many Android tablets will get showcased at Nvidia's press event at CES 2011 and the availability of first Tegra 2 products should happen in Q1 2011.
Engadget hinted at 8MP camera, front facing camera, Android OS as well as 1080p video recording. Nvidia could not get Samsung simply as Samsung has its own ARM based dual-core coming as the successor of the Galaxy S and Qualcomm has a huge steak in HTC as far as we know.
Be aware that Tegra 2 has almost double the graphics performance of Tegra one, which means that gaming could look much better than Rage HD on an iPhone 4, which has set the bar quite high. The potential is there but we are not sure if Nvidia can convince mobile game developers to go its way. It all depends on number of Tegra 2 devices that will ship in 2011.
Motorola should also be coming with its Tegra 2 based phone and even a tablet, but it is not clear when.
