Unfortunately yes. I have some videos which based on this feature, eg. calculating average values with trapezoidal formula (with multistatement easy to sum the area, changing variables with minimal user data input (updating left boundary to old right boundary automatically in each turn, summation, etc...) )

I hope they won't cancel the 991EX or we must to buy until available. This is really big problem in education, in Hungary the 991CEX is preferred in schools and all educational materials based on this model. If they downgrade some features, it will be hard to update without them.
