What do you expect from all this to be in OR/AS?, what new stuff? There's also the question of R/S vs E, what do they retain from each? I'm more inclined to think that Emerald will have a large influence on OR/AS like Crystal on HG/SS. Emerald was meant as the next step and improvement on R/S, I hope they retain the storyline from Emerald (both teams, all three legendaries playing a part) but they switch roles in each version, but I prefer the Wallace/Steven combo over the Juan/Wallace combo, mostly because we don't need two Water-type reps again, enough, we get it, Hoenn is all about water.
