Wolfenstein 2 is more likely to be 30fps, but I just can't see a 30fps Doom cutting it. The new Doom's gameplay was meant to be fast and furious. You can tell this was a huge internal priority. So much so, that decently powerful PCs, don't just hit the 60fps mark, but shatter it completely, and with good IQ to boot!
On top of that, the engine is scalable as heck, so I'd imagine Bethesda would have no problems downgrading the sh!t out of the game to maintain 60fps(if it even comes down to such drastic cuts), especially if they expect folks to double-dip for portability. That said, I think the Switch deserves the benefit of the doubt, at least a bit. In its brief time on the market, it has more than a couple beautiful 60fps games running on it already, with more in the pipeline. Some of those games damn good sitting next to similarly styled current-gen games(Fast RMX vs Redout, anyone?).
The point is; It's not like any of these PS4-XB1 caliber games would need to look like PS2 era games in order to hit 60fps on the Switch. Fifa 18 doesn't look as good as the PS4 version, but it sure as hell didn't require EA to scale back two whole generations to get the incredible results they got. The tiny console has proven itself - since launch - to be well beyond the level of power where 60fps automatically means a game can't look good at the same time too.
I guess having an option between 30fps w/better IQ, and 60fps with certain downgrades is one way to "please everyone." Still, consider me the following camp:
#Team_SwitchDoom@60fps!
