This trailer pretty much confirms my fear that they're NOT using Emerald's storyline and are instead doing that whole awkward split thing from the original Ruby/Sapphire. Which is upsetting.
However, the games do look really, really cool, regardless. Everything's so beautiful and, well, contests look so different if this trailer is anything to go by (was that a Mega Altaria contesting? Eeee~)
Way too hyped for this now *u*
