For anyone praising the music bear in mind it's just Naofumi Hataya's "Sonic3 MegaD Mix", which can be found on the 2009 album, "True Colours - The Best of Sonic The Hedgehog - Part 2". I do believe it was in GEMS collection too. Also, this trailer is great. The gimmicks look fun and it just shows an outstanding amount of work and quality. Looking forward to it.
