I saw another thread discussing OR/AS and it made me think: What features will and will not make it back into these remakes? We know that contests/secret bases are coming back for sure, but what else?
Things that'll probably come:
-GBA Music Player (similar to HG/SS GB Player)
-Rematches from trainers (something missing from too many recent Pokemon games..)
-New islands (apparent from clouds/dark purple thing on the new Hoenn map)
-Battle Frontier
-An extra trio besides the Regi Trio
-Device to make it easier to find Latios/Latias/other roaming legendaries (similar to the Poketech from D/P)
Things they I'm unsure of:
-Newly designed Mirage Island
-The Battle Tower south of the desert from Emerald
-How the Safari Zone will act compared to the original
-How GameCorner functions (if added at all)
Would be cool but very unlikely:
-Sevii Islands (from FR/LG)
-World Championships (from B2/W2)
-"Hard Mode" (from B2/W2)
