I really would like them to keep the original colors as Red and Green. Made no sense to take the original Green version and change it to Blue when the original Blue version was very different. My guess is that if Fire Red and Leaf Green aren't released in the US by then, it'll probably be the...
Celebi was given in a bonus disc in Japan like Jirachi was in the US. Mew is programmed into FR/LG. It has an overworld sprite. But no one knows how to get it. Not even with enough hacking have they found out.
Focus Punch is a terrible Fighting type move. If you're gonna go with a Fighting move for Combusken until it learns Sky Uppercut as itself or Blaziken, you're better off with Brick Break which happens to be one of the best Fighting type moves.

The only kind of Pokémon game in any shape online is NetBattle. And it's only a battle simulator (though a very nicely done one). Nintendo has no plans of releasing any of the games with online play (*fist shake*). The only other kind of online play would be Pokémon Crystal with the GBC Phone...

But the question was..is it possible to trade Pokémon a Japanese Leaf Green, to a US Sapphire? As far as I recall, none of the original games were ever compatible with each other if they were in different languages. So far, English Ru/Sa games can't trade with Japanese Ru/Sa games. So that...
Ho-Oh's also obtainable in Colosseum, so if Lugia and Ho-Oh in FR/LG are obtainable through an unavailable ticket, then that just leaves Lugia, Celebi (outside of Japan) and Mew.
