Everything that B214 said plus the fact that Issei wants to become the ultimate pawn and one of his dreams is to make Rias king of the game. She's not participating in the game until she graduates college and she's still in high school. Issei has been a second year for the ENTIRE story. Based on that timeline don't get your hopes up for a peerage.
