No-one I've spoken to seems to know this.
I've seen the theory that it is because in Japan, a circle has the same sort of positive/accept connotations as a tick does in the West, and the lack of that connotation here is why they were swapped, but I don't buy this: we still have the same negative/cancel association for a cross as the Japanese do, and we don't have any contradictory associations with a circle that would make it particularly unintuitive as a 'confirm' button.

Does anyone have any source on why this decision was made?
Failing that, does anyone have any idea who at Sony would likely have been responsible for the decision?

A programmer on the OS? A marketing guy?
