Hello, I'm a Sega countdown, and I just turned 5.
Check the internets closely. Someone has guessed Sega's big surprise.
Sega's next-360action site was updated to "V" today. That's "V" as in "5," meaning just five more days until this cursed tease ends.
Actually, the tease may already be over for some. The text in the yellow strip reads "It's count 5! When I see a correct guess posted on the 'net, I get excited."
So it looks like someone has guessed the answer.
Which implies that there's an answer that's possible to guess, meaning this can't be an original title.
Or maybe it is, and they're just screwin' with us.
