As much as I like Ico and Shadow of the Colossus, triangle has no business being the jump button. Yes, I know you can map them to other buttons but it still shouldn't have even crossed their minds. When you're platforming, jumping is pretty damn important. That is why jumping is on the X button since your thumb is there anyways. Triangle is situated near the very top of the controller and is made for things you wouldn't need as often x___x.
