According to Staples’ training guides, they sure appear to be taking this tablet game pretty seriously. We already know that they plan to release the wifi-only Motorola XOOM some time around the end of March or early April for $599, but they aren’t stopping there. They are expecting to see the Samsung Galaxy Tab 8.9″ device that should be announced in the coming weeks at CTIA, Acer and Toshiba 10″ devices, and even a 10″ HTC slate. Now, we saw the HTC Flyer at MWC a few weeks back, but that was only a 7″ model. Could a 10″ be the rumored EVO tablet that Sprint is expected to announce in the near future?
