i collect old pokemon games. and im not sure if anyone has mentioned this, but they missed some of the major ones not to mention lots of games released on the side; yellow, crystal, and emerald.
also everything kei has said makes perfect sense. the only thing i havent seen kei talk about is that (as i said above) they neglected emerald. so i bet the third one "Z" will be a dark green color. or, and im not sure why, but it doesnt seem like they would use a color like green for the third. based on the ways they have marketed the previous third games, and what is currently going on on the internet, they will either, as hinted by the black background, and interesting contrast a deep purple, or a solid yellow. the purple from the a mix of the two colors, or the yellow could have be from the original yellow edition, seeing as he hinted talking about more pokemon. (in yellow you could get 151 without trading.) he also talked about the link cable and emphasizes a lot about the connection of these games, also hinting towards a much greater communication setup. which would support what they were saying about the wireless connection from the leaf green and fire red. i thought it odd when he talked about it because it was originally tested with that game. key words be "originally tested" which all adds up to my final conclusion of a dark green game. with all three having a completely different type of connection. one possibly "original" and "new to its time" i also think its interesting they talked alot about the old games and skipped over the new ones, only mentioning their names. which i believe is their way of telling you about the bringing back of some old aspect of the games.
so yea. got bored found a thread and thought about what i saw as much as possible for an hour, maybe overthought it. anyway, just my opinion
