Do you think GF would put out a demo for X and Y maybe a month before release? This would be an obvious first for the franchise and the games will sell themselves anyway, but it could still be a cool little download to increase hype.

What I would put in a potential demo:

>Create character
>Chose starter
>Normal gameplay up until reaching the first gym town (so the first hour or so)
>Be able to catch wild pokemon, battle, level up with a cap of level 10
>Perhaps reveal some new early route pokemon in the demo itself
