The whole situation with Oblivion Remastered feels so strange to me. If I had to guess, Bethsoft has very little marketing budget for this game, being a remaster, so they're doing a marketing by leaks strategy. But even then the leaks are like "It could launch any day now!" And that seems like such a quick turnaround for an unannounced game, though it may have to go through platform related stuff before actually selling. Fire Emblem Engage had something similar happen, but it didn't really sell well at all.
Not really relevant to your post, but the Remaster has been on my mind.
They aren't taking the time to install it, it has way less downloads compared to similarly endorsed mods.
