Maybe the RE Engine is not compatible with the Switch??
Re7 runs at 1080p and 60fps on Xbone S and PS4 slim.
RE2R runs at 1080p and 50-55 FPS on both consoles.
Maybe they will make a cloud version. But Capcom is been giving a lot of excellent games like DMCV, Mh World, RE2R, Re3R and Re7 in the last 3 years.
