Apparently the health bars look different between the two versions, and the flashing/graying effect in B/W will not be present. Does anyone think they are too...choppy?
Who cares about the health bar? Platinum had one black then heartgold and soulsilver changed it back then blask and white made the total hp show on both pokemon without pressing start. It's a new game even the littlest things change. Even the exp bar.
