nRF51822 future hardware revision?

Question

Based on s110 v5.2 release note, nRF51822 will have future hardware revision. 
 What is the change for future hardware revision? Do we need to modify our circuit design for nRF51822 when new hardware revision is released?

I've been allowed to share the most important changes in the new revision, which is: 
 Your sales representative will be able to give further information, and there will also be updated documents on the web when the new revision is officially released. That should happen some time this summer. 
 This future hardware revision should not require any hardware design changes.
