We’ve learned (via NeoGAF) that Sega is teasing a big announcement tomorrow.

The tease was posted over on their official Facebook page, and it reads:

“If you’re a fan of the classics, you’ll definitely want to tune in tomorrow for our new game announcement.”

Following their previous Sonic-like tease, If you consider this year being the 25th anniversary for the Sonic the Hedgehog series, we’re expecting something involving Sonic.

What could it be? A repackaging of their Ultimate Genesis Collection, for modern platforms? Sound off in the comments below!

We’ll keep you guys posted.
