Umm did you actually look at the width of the 65VT30?
From the VT30 thread: 65VT30 with stand (inches): 39.2 (h) x 61.9 (w) x 15.8 (d)
So almost 62" and their site flat out says that the one they have labeled for a 65" TV is if its 56" to 58" wide. It looks like they don't have one big enough for the 65VT30. I'm guessing the extra width is due to the 65VT30 bezel being larger.
