Toshiba released three 10" tablets in July last year, Toshiba Excite Write, Excite Pro and Excite Pure. The first two pack 2K displays (2560 x 1600), Nvidia Tegra 4 chips and 2GB of RAM. 8MP rear-facing and 1.2MP front-facing cameras are also a part of the package along with Android 4.2.1 JellyBean OS and 32GB of internal storage (expandable via MicroSD card up to 32GB). They are pretty much the same except for 1 thing, you guessed it, the Excite Write has a stylus on board. The third one, Excite Pure, has a somewhat lower specifications. The device is sporting a 1280 x 800 display, a Nvidia Tegra 3 quad-core processor and just 1GB of RAM. The device doesn't have a rear-facing camera, but you can find a 1.2MP camera on the front. The device also has a lower storage capacity compared to the first two, only 16GB, also expandable.
It seems like Toshiba is getting ready to launch a new 10" Android tablet. A device with a similar model number to the mentioned 3 tablets has popped up at the Wi-Fi Alliance website. Last year's models had an AT10-A model numbers while this one has an AT10-B model number, which suggests it will be some sort of a refresh in a similar category though. The document doesn't give us much to work with, but it says that the device will have Android 4.4 KitKat pre-installed and will feature a dual-band 802.11a/b/g/n Wi-Fi.
No word on when will the device launch or what kind of tablet are we talking about here, will it be a budget tablet or a high-end tablet. It could be either or just one out of a few that they'll launch like last year, but if they will launch only one I'd bet it will be a cheaper/budget version though. The only available evidence (if we can call it that) is the fact this new tablet is apparently not going to sport a 802.11ac Wi-Fi which last year's high-end models had, though that doesn't have to mean anything.
