OR/AS will have demo versions!
CoroCoro confirmed this yesterday, but now that there are more details available I thought I'd post this.
The first images for this month have started to appear. In this image, from the magazine Weekly Shonen Sunday, it confirms that, in next month's issue of CoroCoro, due out on October 15th, a special serial code will be given. This Serial Code offers you a trial version of Pokémon Omega Ruby & Alpha Sapphire which appears to have you pick between Grovyle, Combusken & Marshtomp and ends with the obtaining of a Mega Evolution. - Serebii
Sounds cool! It gets even better: CoroCoro leaks continued today with more details on the demo.
You will see a Mega Evolution for the first time in this demo, and you can then transfer it, as well as items you collect, over to the main games when they are released. It is also hinted that, if you play the demo every day, something special will happen - Serebii
Also a few other things not mentioned already from today and yesterday's leaks:
- Primal Kyogre and Primal Groudon get new moves, Origin Wave and Cliff's Blade respectively. These are assumed to be the mystery moves we saw in one of the trailers.
- Rayquaza apparently holds some secret to Mega Evolution.
- Mega Gallade remains Psychic/Fighting, and has Inner Focus as an ability.
This month's CoroCoro may not be done just yet, so stay tuned to Serebii's news page since they'll update first most of the time.
