The most notable thing this trailer shows is more of Shadow and Metal Sonic, who appear in both games as either bosses or rivals to race against. Also it has overly dramatic music and an ancient evil because why not.
Straight from Sonic Boom (the event, not the TV show), SEGA just announced that Sonic Boom (the TV show, not the event) will premier in the US on Cartoon Network on Saturday, November 8th. So we’ll be able to see the show before Sonic Boom: Rise of Lyric and Shattered Crystal are released. A sneak preview was shown as well, with the reaction to it being very positive.
As for Europe, the show won’t be appearing in most of that region until Autumn 2015. Well, unless you’re French, the show will air at an earlier unannounced date there. Apparently being in the country where the show is produced has its benefits. The rest of you Europeans can just sit and reflect on just how many more things called Sonic Boom we’re going to get.
Update: SEGA just released the sneak preview online for all to see, be sure to watch it above!
