Even if it was not mod-capable, I would probably still buy it because I've had the itch to play for the last year, but I knew I was getting XBONE eventually, so I didn't want to be half-way through a playthrough and have to convert. Ever since I got XBONE, I was checking weekly to see when it would be backwards compatible. I doubt the mods will be used to clean up any bugs/glitches, as Bethesda remastered Skyrim over Oblivion or Morrowind (other remaster-worthy titles) because it was the least amount of work and it still enjoys a huge following. I seriously doubt they'll want to dedicate serious resources to fixing glitches and bugs when they're in the midst of developing Elder Squirrels 6 and still managing ESO.
