A few days ago, a few websites reported the discovery of a trailer for Sonic Synergy, the game which would become Sonic Boom: Rise of Lyric, the trailer showed a number of differences to the final product, such as some very different Eggman designs, better looking graphics and a completely different title.

Well, a few hours ago, a member on our forums revealed that they had an extended version of this trailer which shows even more differences, and that they had it for 2 years but were under the impression it was already known! Well… we know about it now!

Some of the more noticeable differences include Sonic who has finger-less gloves and his arms are not completely blue, the chao were also going to be in the game at some point.

Check out the trailer and see the differences yourself.
