Diablo IV isn't the only high-profile game rumored to debut at BlizzCon. ESPN claims to have a training document revealing plans to introduce Overwatch 2 at the event, which starts November 1st. The description suggests it may be more of a refinement than an overhaul, but there could be significant changes. Reportedly, it'll have a stronger focus on "story and narrative elements," including a four-player experience set in Lucio's home turf of Rio de Janeiro. You might not have to rely quite so heavily on character origin videos to get a feel for Overwatch's universe.
