Earlier today, a preprint on direct imaging attempts of planets around at Ran / Epsilon Eridani was released: Searching for Planets Orbiting ε~Eridani with JWST/NIRCam. They failed to detect planets in the outer system, setting a mass constraint that rules out at least Saturn-massed planets orbiting beyond around 16 au (according to current models of planet evolution and brightnesses). As for Ægir / Epsilon Eridani b, they did have a possible detection of an object at the expected location with expected brightness, but it happened to land in a noisy area, and hence they couldn't confirm the detection of this planet.
As an additional paper observing the debris discs of this star is projected to be released later, I will continue to wait for this paper to inform my decisions, and my rework of the Ran system in Orion's Arm will not begin yet.
