Gotta split that huge post of yours into pieces. =P First: That's actually kind of ironic when you think about it. xD
Second: True, but why else would four Johto Pokemon seem to have a starring role in a movie, that could've been used to house a gen five Pokemon or two?
Three: Yeah, I heard the speculative community on Serebii got itself all ready. =P
Four: I agree. And maybe give battles a bit more speed like in Plat, and speed the running shoes up a bit more?(Also, is it just me, or does the Bike seem slower in fourth gear compared to Diamond and Pearl? =/)
Five:

I heard that Kanto got massively downsized in G/S/C... But, I'm pretty sure with the amount of space the DS has compared to the Game Boy Colour games, they could fit both an enhanced Johto, an enhanced Kanto that is a bit upgraded, and possibly maybe an additional thing?
Dudebot: You must be another of the victims of the dead internal battery, I think that's a side effect of it... =/ But, that'll help =P
Herochild: You sure? I thought they all died around the same time except for Crystals, which were released later, and probably worked more.
Don't forget Viridian Forest and Mount Moon.
