It's been 20 years since we saw that little blue hedgehog make an appearance in our lives. That little guy is still kicking it with the best of the them. SEGA is proud to announce the release of the new Sonic Anniversary HD trailer that takes us through the ages of Sonic as well as some new screenshots from the upcoming Sonic game, including screens of a new level and character renders of Tails (who will be featured in Sonic Generations). Take a look at all this stuff, it's like gold!
