No, thats not right.
According to the info we have thus far, a silver account will be the same as a current Live account. You will get all the stuff you are used to with a silver account and you have to pay for it, probably the same amount, $50 a year.
Gold accounts cost considerably more per month, $30, but you get access to every xbox game there is. You can download full games and play them whenever. I think you can download both Xbox1 and Xbox360 games onto your HDD.
To all those bitching about paying for a service, come on get real. Nothing in the world is free get over it!
