Sega has something big on the horizon. The company is teasing a live event tomorrow out of Tokyo aimed at fans of its franchises. The tease was vague, but whatever it has in store is coming straight from Sega Festival 2018.

Sega FES is taking place in Akihabra, Toyko this weekend. The timing would be right to finally unveil the Sonic Racing game it began teasing last month, but at this point, it would be hard to call that a surprise. The studio could have something else entirely in store, but we won't know until tomorrow.
