>Do we know for sure if all of these characters will be from Sega?
They haven't outright said so, but considering the projects Sega has in development, it's an easy assumption that they'll be using the free DLC to advertise their other upcoming/recent games (e.g., Shinobi, Crazy Taxi, Jet Set Radio, Golden Axe, probably another Monkey Ball, etc.)
Depending on how long they're stretching this out, I wouldn't be shocked if another Sonic character got thrown alongside them to advertise whatever game they have planned for 2026.
