Honestly, I think Sony is going to be more stubborn than Valve. I saw in another thread where some people were getting approved for their Steam refunds even after passing the 2-hour refund window, so it looks like Valve may already be the first to cave.

Sony’s probably going to continue digging their heels in, though.

From what I’ve heard Valve is already refunding most everyone who asks for a refund given this controversy.
