Sort of. In a very roundabout way.
I'm more looking at the cost difference between bulk Blu Ray discs (which I believe can go for 10 cents) to the cards that the Switch games are on.
In Europe we've had Breath of the Wild (March 2017) and Super Smash Bros. Ultimate (December 2018) go for €70 instead of Nintendo's typical €60, so the answers to your two questions aren't difficult to imagine. Eventually Nintendo games will cost $70 in the USA, but most likely that will be only for the absolutely massive brands that feature a tremendous amount of content instead of Nintendo issuing a roundabout price hike. Aside from that, with the costs going up for almost everything in life right now, people are already quite numb in response to price increases, so video games following suit won't be a surprise to anyone.
As for the cost difference between blu-rays and cards, in 2017 ZhugeEX said that there's no difference for a third party publisher between a 50 GB blu-ray and an 8 GB card. That was five years ago, so today it's safe to assume that a 16 GB card has taken that spot, hence why they've been used so commonly for a while now. 32 GB cards remain more expensive, but when you consider compression rates that have no difficulty to bring down a file size to 25-33% of its original size without sacrificing content, then there aren't actually all that many games that cannot fit on a 16 GB card. Switch game cards are read-only memory just like blu-rays, hence why they are so cheap to produce; there's no rewriteable portion on the game cards, so all game saves are on the internal memory of Switch consoles.
Legend11 correctly predicted that GTA IV will outsell Super Smash Bros. Brawl. I was wrong.
