CoroCoro's latest issue has shown a number of new things in regards to the fast approaching Pokémon Omega Ruby and Alpha Sapphire remakes.

New Demo
It has been said that in next month's issue of CoroCoro, there is to be a serial code for a demo for ORAS. Supposedly, you start off with one of Grovyle, Combusken, or Marshtomp, and the demo concludes by receiving a Mega Evolution. Not much information besides that is known at this time.

I don't like how Mega Camrupt looks like a teepee version of Magcargo. Other than that, I'm liking these new megas. I like how mega Gallade gets a blue cape.

Lots of people are guessing "strong rain" and "strong sun" are going to be the return of permaweather to X and Y. Competitively that's stupid, because they just finished nerfing the weather, but I guess it makes logical sense. Going off the names, I'm guessing they have more exaggerated effects of the regular weathers, like a 2X modifier on Fire attacks instead of just 1.5X, and maybe some other things like residual damage on all Grass types.

Also, one of my favorite Sinnoh Pokémon gets a Mega. Iron Fist and increased Speed, plz. Although from the picture I have no idea how in the world those fists could possibly be iron but whatever.

I love Mega Camurupt. It looks like a train. I'm naming mine Choo Choo

Mega Gallade for Wally °-°
Awesome

Aww yeah Mega gallade! I have mastered Mega Gardevoir, time to master his. (Expecte to see me useing it alot)

I'm digging mega sharpedo xD, thanks for the information.

Serebii posted more stuff guys regarding this current info.

Mega Gallade Stays Psychic/Fighting and Gets Inner Focus as an Ability

Inner Focus for Gallade, when they could have given it literally given it ANYTHING ELSE? ლ(ಠ益ಠლ

Also, I notice it says "all" of Sharpedo's stats increase, as do Camerupt's, except for Speed. So they decided to buff some HP, after all?

I have edited the first post with the new localization information that was seen in the new trailer. For those of you who have not seen it, I have taken the liberty of posting it here...

Serebii has yet have more info about the demo. They said that the West will get the demo too, but didnt say if its for the US or not.

Wow, those weather effects are brutal. Here's hoping only Groudon and Kyogre get them.

I'd be excited for this, but I sense that this is the beginning of a trend of Game Freak re-buffing things they'd emphatically nerfed in this generation. What next, Dragon type going to get some shiny new super awesome type matchup in Gen 7, or perhaps Steel or Baton Pass users?

I just realized that with the strong sunlight effect, Primal Groudon's weakness to Water isn't even consistent, and thus its only consistent weakness is to Ground.

Well, Primal Groudon is shaping up to be pretty scary.

Those weather effects are ridiculously good. Mega Gallade! Inner Focus ain't too bad, but could've been something better. Camerupt will probably remain well in Trick Room, especially in doubles with a partner that has Storm Drain and Sharpedo is gonna be monster with Speed Boost later packed with Stab/Strong Jaw Crunch and stuff.

Mega Gallade
If I do end up playing these games eventually it'll definitely be on my team (along with mega absol and mega lucario)
Now we need mega eeveelutions.
