The imminent launch of XRISM will usher in an era of high-resolution X-ray spectroscopy. For active galactic nuclei (AGN) this is an exciting epoch that is full of massive potential for uncovering the ins and outs of supermassive black hole accretion. In this work, we review AGN research topics that are certain to advance in the coming years with XRISM and prognosticate the possibilities with Athena and Arcus. Specifically, our discussion focuses on: (i) the relatively slow moving ionised winds known as warm absorbers and obscurers; (ii) the iron emitting from different regions of the inner and outer disc, broad line region, and torus; and (iii) the ultrafast outflows that may be the key to understanding AGN feedback.
