Staples has some interesting training guides published recently, mentioning devices that have yet to be launched. These include the 8.9 inch Galaxy Tab that we’ll see next week taking off at CTIA, plus a mysterious 10 inch HTC slate, that could be the EVO model we’ve been hearing about.

Also, there are 10 inch Acer and Toshiba models mentioned as well, all with Honeycomb, plus another 10 inch Dell tablet, with the same operating system. HTC Flyer is a 7 inch tablet, so could the 10 inch newcomer wash the sins of the first model, only featuring an older version of Android during its debut.

Sprint is supposed to launch the HTC EVO tablet, if rumors are correct. I guess that CTIA will be the revealing time for these speculations and leaks…
