Wait up! I bought a case for the Galaxy Tab 3 10.1 when I ordered my Tab Pro 10.1 and the case doesn't work for my Tab Pro 10.1.... So be careful because there's a good chance it will not work...
You may be right though because this one is a leather case with opening on the corners, and the one I purchased was a hard case and covered the corners, so I couldn't get mine to fit into it because of that. From the looks of this one it should work, but better to be safe and take your tablet with you and ask to try it.
