Ok, about the used games thing, predicting how it will fall out.

"Update: In a post answering "top questions" about the Xbox One, the official Microsoft page notes the system "does not have to be always connected, but Xbox One does require a connection to the Internet." Additionally Microsoft notes that in the case of pre-owned software, the Xbox one is designed "to enable customers to trade in and resell games. We'll have more details to share later." The Q&A makes no mention of the fees confirmed by Microsoft to Wired.

Update 2: The Q&A post from Microsoft's official page appears to have been removed, we are investigating"

In the official Q&A they stated that you would be able to buy/sell used games (atleast for an hour or so). What if that somehow linked directly to the retailer and you'd buy digital content (since the discs are only used to install).
Basicly you 'sell'(unlink the game from your account), that transaction gives store credit.
For that credit you could get some money to use on buying a new game, the 'fee' for unlocking games = almost full price.
(a 10$ discount, what you get for trading your game)

MS gets a cut, retailer still gets a cut & developers get some money too. all digital used games

Fucked up baseless guess or do you think this is the way it will go?

Take a goooood look at that and think.

"What would EA do?"

There you shall find your answer.

Use origin for everything? :)

It should stay as it's always been. Once a new copy has been sold, it's up to you what you do with it, it's your property once you bought it

Yeah, don't get me wrong.. I like beeing able to get a used copy of something and beeing able to play it afterwards.. no strings.

So they didn't comment on it?

new stuff here:

"UPDATE 2: T3's deputy editor added the following on Twitter: "[MS] told me that once you sell a game, the license transfers in the cloud. So a new gamer activates it, it's removed from yours.""

"UPDATE 6: MCV has now spoken to a Microsoft PR representative. The official line is as follows: “Xbox One will run pre-owned games. It will not block pre-owned games. We will additional details at a later stage."

Ok thanks. Hopefully their is no fee to play a used game otherwise my gamefly service has to go since it will no longer be useful. 

Some reports did say "there will be a fee" etc. , that was also stated on the official FAQ, but is now removed.
I'm still confused as hell about it :S
edit: oh, the 'fee' was mentioned in the interview with wired, wasn't stated in the official FAQ(Q&A) thread @ MS. my bad.

This is my hang up. I hope it isnt true, i want both the PS4 and XB1. Im glad i have a choice at least.
