SEGA had originally planned to make some Sonic the Hedgehog announcements back at South X SouthWest, but that ended up getting squashed due to the pandemic, which then further pushed any/all announcements out of the way. Fans have been wondering why nothing has come out since the original announcement delay back in March, and now SEGA has shared an explanation.
According to a portion of SEGA's team, SEGA has worked out a new delivery method for revealing this Sonic content, but they just can't make it work right now due to the pandemic. They seem to really like this plan they have in the works, but making it happen just isn't feasible at the moment. Rather than abandoning this idea, they're working behind the scenes to see what they can tweak or make happen in order to move ahead with this presentation plan. No set time for a reveal just yet, but SEGA is doing the best they can to figure things out.
