I don't hold my breath on that.
It's 4 times faster than the original SD Express, and about 6 times UHS-III, which is great. But look around at the SD cards you see in stores: Even just UHS-II is still relatively rare as they are much more expensive than normal UHS-I cards.
I just checked for 128GB (which is already above what most people buy except for the Switch) and UHS-1 prices went from 20-60€. UHS-II started at 140€, and I couldn't even find just one UHS-III, let alone a SD-express card. Of course with such a price difference only absolute enthusiasts or people who absolutely need the plus in speed will buy the faster onesLast edited by Bofferbrauer2 - on 20 May 2020
