It's not the law here, but I can get a full refund because demand is high on the console. But I've pre-ordered other things and was told I'd lose a small deposit due to the store having to purchase it after I put in the pre-order.
I didn't realize some places restricted you like that. The places I preorder from either take a small deposit that is refundable, or require nothing at all. I mostly preorder from Amazon now and of course their policy is the best since you can change pre-orders very easily.
Regarding a quote from the article, here is the relevant part:
The Xbox One taps into the power of the cloud quite a bit. We're seeing one of your competitors, Sony, doing backwards compatibility through streaming. Does the cloud-powered nature of the Xbox One leave it open for things to change in the future for something like that?
Yeah, absolutely. That's one of the things that makes [the cloud] at the same time both totally interesting and hard to describe to people. Because what the cloud can do is sort of hard to pin. When you say to the customer, we want the box to be connected, we want developers to know that the cloud is there. We’re really not trying to make up some phony thing. But there are so many things that the servers can do. Using our Azure cloud servers, sometimes it’s things like voice processing. It could be more complicated things like rendering full games like a Gaikai and delivering it to the box. We just have to figure out how, over time, how much does that cost to deliver, how good is the experience.
Like I said before, it seems MS is pursuing these features, but they are still a ways off. Now we know Sony plans to get Gaikai going sometime in 'early' 2014 for the US and an unknown date for Europe, but it sounds like if MS is going to offer something similar, it will be much later.
