We are planning to roll out NextGen UI soon and I'm just wondering if anyone knows where the roll out materials are?
Hopefully, this link will work, but if you have the correct permissions, you should be able to go Administration --> Expense --> User Experience Settings. On the page, to the right of "PREVIEW NEXTGEN UI FOR CONCUR EXPENSE AND CONCUR REQUEST" there is a link for "Learn More".

Hope this helps,
