Diablo 2 Resurrected was easily the biggest news (even if it had been leaked ahead of the event) coming out of BlizzConline 2021, with Diablo fans excited to dive once again into the classic action RPG that's being remastered by Vicarious Visions.

Diablo 2 Resurrected will also ship across PC and consoles featuring cross-progression, which is great news. Even greater news would be having cross-play and in an interview with Eurogamer, Blizzard did leave the door open for that happening at some point after launch.
