i dont think there would be price cuts on higher end parts, because thats the name of the game.. its a long term thing and nvidia isnt going to shift that for short term gains..
what might happen is that more volumes will start shifting to lower end cards or oem opportunities, and respun 30 series cards to partially make up for lost revenue opportunities..
you would have some strange sku's that dont take the sheen off nvidia's tiered branding but still deliver the desired revenue impact
nvidia is not going to base either decision on short term memory, they would be looking at normalized growth rates because the last couple years have been actually an outlier, and not a true reflection of sustained market demand
amd is going to be hit harder by the contraction in demand, because they dont have nvidia's global reach and they would have to really invest in unreasonably higher inventory levels to match nvidia's availability - my best guess is amd isnt going to do that when the market is actually contracting, so you'd have a vicious cycle unfortunately
layoffs are a reality now, however you look at it
