How is Square Enix going to pad out Midgar?

I guess that making all 8 sectors explorable (both upper plate and slums) would help. I'm guessing the ghost thingies that harass Aerith, might make a sidequest out of it. Oh no...

They might make Mako Reactor destruction missions...
In the original game Reactors 1 and 5 are destroyed, yet by the time SHINRA uses the Soster Ray against Diamond WEAPON, all 8 reactors are functional...

Will we have "dates" like the original had the Gold Saucer date?

Will we have a crappier version of the Gold Saucer arcade with Crazy Motorcycle Chase as a game and maybe a few generic games?

Will they introduce a Children's Card Game like Triple Triad to pad the game?

Any of the Crisis Core stuff? (Genesis, Angeal clones, reoetitive quests?)

Maybe Cloud will have some hallucinations involving Silver-haired Momma's Boy? We kinda saw that in the trailer... I mean unnecessary boss fight against Sephiroth to cement his place as bad guy. (We know that was actually his mom!)

How do you add 54 hours of gameplay to a 4 hour segment?
