Ahh the good old "shit, I was wrong, let's point to something minor, so they don't notice that I was wrong". But what's funny is "a 16Gb cartridge costs the same as a 25Gb bluray" without any source "tiz iz tru becoz y sayd soh". I can buy a 25Gb bluray for about 1$, good luck with your flash memory at that price.
I don't have any doubt about your intentions but I'll say anyway that we had reports of 8gb switch cartridges costing the same as a 25gb bluray at launch in 2017. It's been 3 years and those things get cheaper.
