FR/LG had plenty of extra post-game areas/events, and the rom size wasn't that impressive.
The rom size wasn't impressive as it was a GBA rom and there is a lot of difference in GBA roms and NDS roms. On topic: Hoenn will be cool but only if it doesn't affect the kanto and jhoto parts very badly. As I have already said hoenn is very unlikely to be in but just lets see what happens next. Maybe Nintendo and Gamefreak may surprise us big time!
I also hope you realize that the maximum size of GBA and DS roms are the same.
I am sorry for that. I didn't knew that fact. I always thought that the maximum size of a GBA rom is 32 mb and the maximum for NDS roms is 256 mb. Can you please tell me where you got that piece of information?(Just asking. I am seriously not trying to be rude or something!)
No Hoenn? Pleh. Consider the storage space used for the DS game cards (2 GBS), the SDHC (32 GBS) and not to mention, the fact that Game Freak has their special way of always adding more fun to their latest games.
Hoenn should be in this game.
Also, take notice of Kanto obviously being in there. This could render the GBA migration process useless.
DS-i anyone?
Myoko-chan as far as i can tell your referring to the archive size which is the expanded size of the rom. As for 254mb being the maximum for this you are WAY off i just had a very quick look and found one that is 2024mb Dragon Quest IX: Hoshizora no Mamoribito. So there is no question of whether or not they can put it in but more will they put it in.
I'm still undecided on this one as i didn't like hoenn because well it bored me to no end, almost all the pokemon added are bad excluding the pseudo-legendarys, swampert and breloom which i think are the only ones who see any competitive play anymore.

Game size does not expand; what you seem to be mixing up is Megabits (Mb) and Mebibytes (MiB, or erroneously, MB).
The theoretical maximum size of a GBA game is 256 Megabits - 32 MiB. The Game Boy Advance development kits are designed to work around this limit as the programming pointer system can only address 256 Mb. On the other hand, the theoretical maximum size of a DS game is much much higher than 32 MiB. We've seen 256 MiB games, so if that's all we'll ever see, the maximum would probably be 2048 Megabits.
Getting back on topic, the hurdle with including Johto would be development issues, costs or time. It should be said that FireRed and LeafGreen use about 5-6 MIB of the 16 MiB available in its game cartridge - a ROM hacker could tell you that much more could be stuffed in. Platinum didn't use all of its available space, either.
