The rematches is a very excellent addition. Why wasn't there in Black and White 1, was the question I first thought. I prefer battling the gym leaders over the Elite Four anyway to be honest. If they do not add that feature of the rematch for Black/White 2, it will be a huge disappointment. I can't believe I totally forgot about this earlier I would had loved to battle Elesa/Skyla over and over again like I did with Whitney, Erika, Claire, Misty and Sabrina in HG/SS. Come on, don't disappoint us!
