Unless they plan on developing a new non-graphing scientific calculator, but then why keep the same name? It is just a bad move, happens all the time, companies make mistakes. As most have concluded, as far as Casio is concerned, the FX-991EX and similar models are the way to go. As for me, as an engineer, there are better choices for calculators, which use is now really limited to exams. I do all my calculations using SMath Studio, similar to MathCAD. And perhaps this is why Casio is focusing on middle school math, rather than advanced engineering. There was a day when a calculator was an essential tool for everyday science and engineering, now its just for exams.

As far as the name (model number) is concerned, there is a certain logic to Casio keeping the "115" or "991" in the name of any new non-graphing model in this category.

"Casio - The NCEES approves all fx-115 and fx-991 models for use on its exams. Their policy states that “any Casio calculator must have ‘fx-115 ‘ or ‘fx-991’ in its model name.”"

Cases in point: the ES versions of the 115 and 991 have been reincarnated as 2nd editions. So it looks like the function set of each seems to be accepted and sanctioned as standard choices for schools.
