We’ve seen Samsung’s 7-inch Galaxy Tab, along with the new 10-inch that the company announced at Mobile World Congress around a month ago. Now, this new advertisement gives us a surprise that we weren’t exactly expecting. On March 22nd in Orlando, Florida Sammy is set to announce exactly what they’re keeping from us. While the “78910″ gives us clue that it’s likely an 8.9-inch version of the Galaxy Tab, we can never be too sure.
