It was awesome seeing this being revealed live! I'm really looking forward to this show as the writing and characterization continue to be the strong points of the Boom brand.
As for Sonamy - oh, that's pretty much confirmed. During the live reading, they had two scenes. One was where a robot was reading everyone's thoughts... it almost revealed Amy has feelings for Sonic. Similarly, when Sonic hears Amy is setting up for a date with someone else, he immediately is shocked and offended.
Oh man! This may be the funniest Sonic show yet! 
My favorites being Sonic's nonchalant slide through the laser barriers and Sticks' paranoia of her own shadow.
He's sleeping actually, I think. Based on his expression and the fact Tails turns them off. Sonic also has dark lines under his eyes in the first few seconds, indicating he didn't get much sleep.
