• We'll get full seasons, but it will be about 30 episodes or less, continuing the trend of increasingly shorter seasons during the Disney Era
• The Shinkenger adaptation would either try to work in the Japanese references or craft an entirely different story. Maybe something akin to Amit Bhaumik's proposal would be used. At any rate, I have more faith in Disney pulling it off.
• The Goseiger adaptation, too, would be a better effort, with more characterization and a better story.
• The opening theme songs would not be remixes of "Go Go Power Rangers"
• On the flip side, production values would not be as strong as Saban's. The special effects and cinematography wouldn't be as good. Remember that RPM was still in 4:3 standard definition and for three years since Boukenger went HD, they used visibly squashed Toei footage for many scenes.
• Power Rangers would likely fade even more into obscurity. It might be placed on less popular channels, and large parts of the world might not have shown it, like here in Australia or New Zealand. Disney would not bother to market it to the level of Saban's and Power Rangers would remain a niche show instead of the blockbuster it is now.
