I don't really see how you can make price predictions with that sort of info...
We're talking about one specific company here, while there are tons of other players on the market.
Is it possible bitmain or another ASIC manufacturer is ramping up production and flooding markets, leading to nvidia experiencing a significant decline?
This would be my first thought as well and if you look at Bitmain's profits from 2017, it seems pretty clear that they're dominating the market

after the price of Bitcoin rises, Bitcoin's value doesn't go up because of increased miner sales.
