Hmmm in the circles in the battlemode window, you will see numbers (red for enemy green for rsc node).

Don't ask me why it's numbers instead of letters now but it doesn't change much since the letters where different then the wiki map ones anyway. for example in orel 10 is node J and 11 is node K compared to old prediction.
