So what is it? Is it going to be 28nm Quad-core 2Ghz with Nvidia's Geforce 9 series GPU?
Hexus.net speculates that Tegra3 might launch during Mobile World Congress, that is to be seen. As the event likely is going to be a launch platform for plenty Tegra2 devices, Nvidia might not want to pre-announce Tegra3 too early, as it could maybe be argued it did announce Tegra2 a bit early at CES 2010 compared to when devices are actually shipping nearly a year later using the processor.
One thing to look for in Tegra3 may be faster memory bandwidth, faster memory I/O performance, DDR3 RAM (if that's not supported in Tegra2?) all of those for smoother multi-tab web browsing performance. As far as I've tested using Firefox on Motorola Atrix 4G and Toshiba AC-100 that multi-tab web browsing can cause slow-downs. Tegra3 could use full 1080p@60fps full codecs full bitrates playback (Tegra2 seems to have problems even with smoothness at 1080p@30fps).
