Simple response/answer to Sony that took me seconds to realize: when people see a triangle, they call it a "triangle." Same idea for a square and circle. However, I (and I think that many would agree) don't think that the button in question would be referred to as a "cross" by most people. A cross to most people is what people (like Jesus) were left to die on back in the day. In other words, the easiest thing to associate with the "X" button is the letter. It's possible that in Japan, people refer to that as a "cross." However, it is definitely not common in other countries (such as Canada and The United States) to think of it as a "cross."
