Two questions about Xbox Live

I am planing to buy Xbox One at the of the year. But my Xbox Live Gold will expire before that. If I renew my Xbox Live Gold for a year, will I get Xbox Live for Xbox One also?

At the end of the video, it says: some features require Kinect (Fall 2014). What does that mean?

Xbox live subscription is associated to you GT so it will carry over.

It means that in Fall 2014 some features will require Kinect.

Now, you modified my signature, so can I put one picture?
