There's currently a mystery Bethesda title up for pre-order on Amazon US, as spotted by the eagle-eyed Wario64. It's a full price pre-order at $59, and it's listed for PS4 as well as Xbox One and PC. It has a placeholder date of 31st December 2019.
It's already a bit suspicious, but things get even more eyebrow-raising when you watch the placeholder trailer that's attached to the product. Again, courtesy of Wario64:
In case you're unable to watch it or it gets removed, it's number cards counting down from 10 to 1. It's very Fallout, and the slight green tinge makes us think of Fallout 3. Naturally, we're not the only ones who have come to this conclusion, and so there's already a lot of speculation over whether this is a leaked listing for some kind of Fallout 3 remaster... Or even remake. Knowing our luck, it'll end up being something to do with Fallout 76. Sigh.
It's probably best not to get your hopes up, but it's certainly an intriguing find. If there is indeed anything to this and it's not just some sort of cock-up, then we have to imagine that an official announcement can't be far off.
We'll be keeping our eyes peeled.
