Update: The Doom 64 page at nintendo.com has some new screens showcasing the game's environments and a couple of new monsters, and they look good—still very obviously old-school Doom, but brighter, sharper, and more colorful. There's also an interesting tidbit down in the game details, where two developers are listed: id Software, and Nightdive Studios.
Id is the original creator of Doom, which you might already know. Nightdive has also made a name for itself in recent years by resurrecting old shooters like System Shock, Blood, and Turok. If it's involved in the project, I would say that the odds of a PC version (which I think were pretty good to start with) just got a whole lot better.
Original story:
Yesterday, Doom 64—originally released in 1997 for the Nintendo 64—was rated by the Australian Classification Board. Today, it was announced! For the Nintendo Switch. Sorry.
"But wait," I hear you saying. "This is PC Gamer, not Nintendo Gamer. Why are you reporting on this?" The answer is, basically, that hope dies hard, and Bethesda is very specifically not saying that this Doom 64 will be exclusive to Nintendo, like the last one was. In fact, I'd go so far as to say it's suggesting exactly the opposite.
that'd be neatSeptember 4, 2019
Also bear in mind that Doom 64 Aussie rating (it's still not listed by the ESRB or PEGI) says it's a multiplatform game, and that a PC-specific rating briefly blipped on the PEGI site in July. That's not a guarantee it'll come our way, but taken altogether I think there's good reason to be optimistic.
Doom 64 is coming to the Nintendo Switch on November 22. Today's full Nintendo Direct stream is below—the Doom 64 announcement begins at 16:55.
