Are people expecting ORAS to be full of legendaries to be caught because of HGSS? HGSS was an interesting remake where you could catch a good portion of the pokedex without trading over from DPP.
Hmmm...
Gen 1: The Legendary Birds and Mewtwo can be obtained from XY. Mew is obviously an event Legend for this game -- Faraway Island.
Gen 2: Events aside, the Legendary Beasts were last obtainable in HGSS. They might roam Hoenn post-game. Lugia & Ho-oh might be obtainable if Navel Rock is accessible.
Gen 3: Regi Trio, Weather Trio, and Latis obtainable in-game. Deoxys and Jirachi are event legendaries.
Gen 4: I expect the Creation Trio, Darkrai, and Manaphione. Regigigas is a must. The rest, I doubt it.
Gen 5: I don't expect any Gen 5 Legends. It can easily be traded over.
Gen 6: We just had XY. There aren't even much Legends to catch anyway.
It would be cool if we could get a similar Safari Zone system as the one from HGSS. Would you rather have a HGSS style safari or stick to Friend Safari?
I prefer the Friend Safari and I think it will be merged with Hoenn's Safari Zone. This is how I think it will be done...
The Hoenn Safari Zone have 6 areas and each area obviously have default Pokemon.
We select a Friend and 3 additional Pokemon will be found in the wild. It's up to us to find them.
Also, I expect the Pokeblocks to affect the distribution of wild Pokemon, rather than just the natures as it was in the original.
