How to transfer app and data to new Window phone

[Con Chuot]

I am currently own a Samsung Focus S with WP 7.5 on it. I am going to buy Nokia 920 as soon as it comes out. I hope that someone can help me with my questions. How do I transfer all of my apps, data of the apps form Focus S to Nokia 920. I do have about 25 apps and games. I do not want to re-install manually one by one and re-enter data to the apps. Please help if you have a procedure or solution. Thanks.
