I might if I didn't just get BG3. I'll still get it pretty close to launch barring serious issues, though. Everything I've seen about the scale and what the game is is what I've been waiting for for a while.

I know Bethesda isn't perfect and I didn't love FO4, but it's in large part because of the reliance on VATS for combat instead of making guns feel OK. Gunplay looks a lot better and more dynamic and just that combined with Bethesda's world building/sense of exploration (which exists in Fallout, too; it's just overshadowed to me by the mechanics) are super promising. There are always bugs with anything as ambitious as Bethesda makes, because it takes dozens of hours of testing per 10 minute encounter to comprehensively test one, and you can't exactly unit test video games (though we might not be super far off from training AI to supplement human testing), but I rarely experience anything near as annoying as the vitriol implies and I just don't care.

I get the don't preorder principle, but it's on steam. I get to have it downloaded ahead of time and ready for launch, and if there actually are issues it's extremely simple to get my cash back. Refunds make as much (or more) impact as waiting to buy it, so if a game is actually broken my voice is theoretically louder anyways.
