I liked the idea of having two rivals in the B/W version, each with different personalities, I wish that sort of thing will happen again.
I don't really care about names, but I think that one should be quiet and mature and uses a lot of status moves on their Pokemon, whereas the other one has a a chic-like aggressive personality like Hugh from B2/W2 and uses lots of attacking moves on their Pokemon. If there are two rivals, maybe they can ask you to trade for one of their Pokemon. That would be exciting! :)
