In recent news, there is a rumor speculating about potential Mega Evolutions to be revealed by the time that OmegaRuby and AlphaSapphire are released. Here's the leaked picture that is appearing all across the forums. Another thing to keep in mind is that this picture has been floating around for a few weeks already.
In the screenshot we have Primal Groudon and Primal Kyogre alongside the three Hoenn Mega Starters. The silhouetted Pokemon on the bottom form left to right are: Ludicolo, Shiftry, Sableye, Sharpedo, Camerupt, Flygon, Zangoose, Seviper, Salamence, Metagross, Latias, and finally Latios. It's very coincidental that just this week we got Mega Sableye confirmed just this past week during E3. What's also interesting to point out Megamons that are part of Gen III such as Manectric, Mawile, Aggron, and Medicham are not shown in this list. This could mean that this list is mainly for new Megas that haven't been confirmed to have appear as this makes. While both Mega Latias and Mega Latios have been confirmed to be inside the data of XY, who's to say that Nintendo and GameFreak have confirmed this themselves. They could even make give them a redesign to better suit the Gen III remakes. Who knows?
Another thing to point out are Sharpedo and Camerupt, Pokemon that belong to Team Aqua's Archie and Team Magma's Maxie respectively. Interesting enough, if you pause the trailer at the right moment you will notice something that Maxie and Archie are now wearing.
You guess it, much like Lysandre from Team Flare had a Mega Stone, so do Maxie and Archie and judging from this list I think Camerupt and Sharpedo will be receiving a Mega evolution considering they are the Pokemon always seen or thought of when you think of Maxie and Archie respectively.
Moving on to another subject, from screenshots released this past week during E3 we get a glimpse of the overworld of the Hoenn region and how it looks. For now I will use only a few screenshots, but will be providing all known screenshots later on today.
It's obvious that this game is using engine that was used in XY and will have a 3D landscape and world of the Hoenn region. The game looks very beautiful and from these screenshots we can actually gather a view points and features that may or may not be part of the game. I know what you guys are thinking: Are Pokemon going to be following us around like in HeartGold/SoulSilver? While I do love that feature being prominent in the Gen II remakes, I think it's safe to confirm that we are
not going to have this mechanic. Now you're probably going to say to the lines of "But the game is large enough to support this feature", that's not entirely the case. One reason why the walking Pokemon feature was doable in HeartGold and SoulSilver was because the Pokemon were able to be compressed into 1-2 overworld slot pieces because the game was in 2D in the sense that the games were simply a top-down view game where as in XY, the game was designed to be a 3D world with axis of depth, the Z-axis, to make the game in 3D. Also take a look at the screenshots you can see the scale of Pokemon have been made to make it more realistic. Look at those Poochyena. For small creatures conapred to other Pokemon, they take up a lot of space in the overworld. Thus if one Pokemon is too big to shrink down to scale to still make realistic, take for example Groudon, Kyorge, Rayquaza, and Wailord just to name a few, then be upset or not but I don't believe that we will be having the walking Pokemon feature return for the Gen III remakes. However if you look at the screenshot of May speaking with Steven Stone, on the top right corner you will notice a very small black hole on the mountain wall. If you remember correctly back from Ruby/Sapphire/Emerald, this was an area for a secret base. While people wanted the walking Pokemon feature, I think the secret base is better for these remakes as the bases were a main feature for Gen III.
