Welcome to the forum, Maurice. The only thing I would suggest is to also consider the Pentax KP as an option. For most people, the decision between the two models hinges (yup, yup) on whether they want a fully articulating display like the K-70 has, or up/down articulation (KP) is enough for them. If the latter, consider the KP because it has advantages in other areas - too many to list here.
Knowing your budget will help, and whether you plan to keep some spare money for lens purchases (I realise as a istD owner, you have at least one lens already).
In case you want to cast your net a little wider, here's a quick graphical feature overview of recent models (only the K-S1 is missing, but it's broadly similar to the K-S2,
sans weather sealing and articulating display):
