Now that the games are nearing release, it's been announced that there will be a playable demo this upcoming weekend in Japan on the 17th and 18th, the 20th and 21st, the 24th and 25th, and the 31st and the 1st of September. There will even be a demo in Gamescom over in Germany next week. Who knows if this will be the same demo, and that it's just spread across more areas as time goes on, but I think it's a good time to speculate what the demo will present.
It's been stated that the demo will focus upon Mega Evolution, but like all Pokemon demos, more things will be discovered than just more Mega evolutions. In Black/White's demo, there have been newer Pokemon discovered, as with Diamond/Pearl's demo.
What do you think the demo will showcase? Obviously mega evolutions, but perhaps new ones? What about new Pokemon? New evolutions that aren't mega? Perhaps new areas? Anything else relevant?
I'll update the thread and this post when the demo comes, and if there's anything relevant that is shown.
