Pokemon Omega Ruby and Alpha Sapphire

[Koh]

I'm wondering if they'll bring those legendary Islands back for visit, for a chance to get those Legendaries (Mew, Deoxys, Lugia & Ho-Oh, and I think there was one more?). IF they're all DLC though (AKA, WiFi Connection to get the Tickets), they'll be subject to the same fate as the GBA games; once the events end, they're forever lost in game memory with no access.
