18 pages of Black and White news? O_O This is must be a record...at the rate this is going, imagine how much will be in next month's CoroCoro.
Anyway, there is too much to comment on in one post, so I might make another later on.
I like the idea of having three rivals...it was one of my wishes for this generation. I could see some interesting stories stemming from the idea of a "threesome" (i.e you, Cheren, and Bell), and I think a triple battle with you, Cheren, and Bell will happen against the evil team at some point. Speaking of the evil team, as Pokequaza said, I hope N is not the leader of the evil team. The more good NPCs, the better. Two "villains" (assuming N is one) would be pretty neat, and I would like to see how GF works out the story. Most of the rumors with the "Team Plasma" group have been proven true thus far, so I'm not terribly concerned about N being the only villain. It seems that the characters also have a bit more depth to them than in previous generations, which is nothing to complain about.
The version-"exclusive" cities also seem to fuel the idea of a technology vs. nature theme. While one version of the city looks super-modern, the other looks like a much primitive and older. Since Black City is in Black and White Forest is in White, here is how I think a "technology vs. nature" story might play out:
In Black version, Team Plasma is trying to "get rid" of nature, and replace it with technological things. At some point in the story, Reshiram will appear to stop the destruction of nature, possibly in Black City. At this point, you would have the option to catch it.
In White version, Team Plasma is trying to "get rid" of technology, and replace it with natural things. At some point in the story, Zekrom would appear to stop the destruction of technology, possibly in White Forest. At this point, you have the option to catch it.
My whole basis on this is that Reshiram seems to represent nature, while Zekrom represents technology. These version-exclusive cities also seem to suggest some kind of change of nature and technology between the versions.
Another idea for the plot is that N is the main villain, trying to implement his ideals. Since Reshiram and Zekrom as a duo represent Yin-Yang, (i.e a balance) one of the them would appear to try and stop his separation of Pokemon and people. This also explains the titles Black and White. N is trying to make a "Black and White" world in a world full of gray.
These two stories could also be used together. What if...
Pokemon = Nature
People = Technology?
If this was true, then the two plots could easily mix together. I think this could be pretty cool if both plots...we would finally get a good story, or at least one better than most generations. (Looking at GSC and RS here, mostly...both plots were easily laughable, while RBY and DPt weren't all that bad) And btw, we all know how N is trying to separate Pokemon from people.....I wonder if at some point N would rob your Pokemon, to fulfill his ideal world? I certainly hope so. ;]
(To think I only commented on about 4 pages of the CoroCoro...)
