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 ones

Pretty much this. We might seem some positive impact on our day-to-day devices maybe in 4-5 years, ie when the price drops from the probably massive release day msrp's.
