I'm not expecting the other parts to get the midgar treatment, because if that happened the remake would finish in 2040. That being said, I'm not convinced that they can cover such a massive amount of material, fleshing it out to modern standards, in two games.
As a reminder, we still have: Kalm, the Nibelheim flashback, chocobo ranch, the marshes, the mithril mines, Fort Condor (?), Junon, the boat trip, Costa Del Sol, Corel, Gold Saucer, The Desert Prison with Dyne material, Gongaga, Cosmo Canyon, The Ghi material in the caves underneath, Nibelheim again, Shinra Mansion with Vincent and Sephiroth, the mountains with that annoying spider boss, Rocket Town, sailing in the Tiny Bronco, Gold Saucer again, the date with someone, the temple of the ancients and the heavy plot stuff that goes down there, Gongaga again, Bone Village and the digging for the Lunar Harp, The Sleeping Forest, the Forgotten Capital or whatever it's called, the Icicle Inn village with the Gast material, the snowboarding, the travel through the snow and mountains, the North Crater with the big drama material, the Highwind Execution stuff and the escape, Mideel, the big Materia Quests which involve the train and Corel challenge, the Mideel Cloud and Tifa psychological bit, Rocket Town again and travelling through space, Return to Midgar and settling things with Hojo, Wutai with the Yuffie material, the actual crater area, and finally the battle with Sephiroth.
Have fun breaking that -- in a modern, fleshed out style, where certain things could well be expanded upon, like Lucrecia or Zack -- into two games.
