As usual, expect four expansions for each quarter of 2020, with 3.10.0 to be announced sometime in late February. Don’t take that as gospel, though: Release timing for these expansions could vary by a week or two to accommodate holidays and testing schedules.
There’s also, of course, the big 4.0.0 update still in development, which should have some more content reveals ready by the middle of the year — possibly by the time E3 rolls around. On the subject of 4.0, there’s still no confirmation on whether a public beta will be available by late 2020; again, timing is nebulous here.
Grinding Gear Games is also pushing forward with development of the mobile version of the game, taking feedback from ExileCon players and working on things like the Android version. The studio is also hoping to expand its console team in order to develop features for console versions of Path of Exile more quickly. Overall, it’s going to be a busy 2020.
