I hope they keep all the same features from Gold & Silver & add some new things.
One of my favorite things about G/S is that you could travel to Kanto and could get a total of 16 badges (between both Johto & Kanto).
I'm also hoping they keep some of the same background music & remix them a little like they did with FireRed & LeafGreen.
I loved the music that was playing when you're in the Bellsprout tower lol.
BTW, do you know how to capture Dialga in Diamond?..I cannot capture it even the Master Ball and its life is already critical, and in the end I lost many times...
