Sonic the Hedgehog 4: Episode I seems all but a distant memory now, but SEGA is ready to revitalise your nostalgia for 2D Sonic games by officially revealing Sonic the Hedgehog 4: Episode II tomorrow.

Gamespot will have the exclusive teaser trailer tomorrow, with SEGA brand manager Ken Balough keen to emphasise its teaser-y nature; don't expect a full-on information blowout, but we should hopefully get confirmation of its formats at least.

And yes, SEGA did just announce a teaser with a tease.
