Makes sense, it's easily the most dated of the games and has never had a console port (One was planned but dropped). Guessing in addition to a much needed graphical overhaul (The game looks somewhat dated even next to games from the same time, whereas 2 and 3 still look pretty good) they'll make the mechanics more similar to 3, and mainly streamline the quests a bit, especially the somewhat confusing fetch ones.
