Toshiba's had a bumpy journey so far with its Android tablets so far, as we can attest. Now, a fresh leak suggests Toshiba's next slab will house NVIDIA's new Tegra 4 mobile chip (clocked at 1.8GHz, according to an AnTuTu benchmark) and almost the very latest version of Android -- that's 4.2.1, if you've been keeping count. According to techblog.gr's stolen glances, there's also a dockable keyboard with chiclet keys, but no trackpad. It appears to be more of a standalone dock than connected lid, with the tablet connected and propped at an angle rather then joined at a seam, although it may lie on top of the tablet to protect the screen when not in use.

We also got a peek at the ports along one of the edges, which includes micro-USB, micro-HDMI and a microSD slot, but no word just yet on internal storage and, well, much else at this point -- not a digitizer in sight. We've added a shot of the keyboard add-on after the break and if you're interest has been piqued, there's more photos at the source.
