The big show in Texas will commemorate the 25th anniversary of id Software's masterpiece.
QuakeCon 2019 "will include all-new Doom-inspired activities, events, exclusives, developer panels, hands-on demos, new information about Doom Eternal, and a few surprises we aren’t quite ready to talk about," Bethesda said. "All while continuing to feature everything you already love about QuakeCon."
Quakecon 2018 was much better than E3 2018. so expecting same. quakecon become bigger and better than E3 thanks to id software the greatest developer today. more info on Doom Eternal means Doom Eternal will release fall 2019. it wont release before july.
I really hope after Doom Eternal. they will make single player Quake 1 Reboot.
