According to Eurogamer, Bethesda will be announcing Prey 2, The Evil Within 2, and Wolfenstein: The New Order 2 during their Press Conference at E3.
While this is the first time anyone has heard about The Evil Within 2 being in development, the other titles do have some traction to go on. Prey 2 was previously rumored for an announcement by Kotaku and voice actress Alicja Bachleda-Curus said in a TV interview back in September 2015 that it was in development and was going to take 2 years to develop.
