After the release of the new Casio FX-7400G2, we feel there is no real change in the hardware in particular the user memory. So there is no immediate plan to do a newer version of Insight for now. We may do something about it in 2012, but surely not this year.
We hope the current version of Insight is sufficient and all of you will be able to find ways to improve the code for your personal use. 😀
