I know this is off-topic, but... I would love to see Flying Bark Productions make a Jet Set Radio cartoon with the same energy as Rise of the Teenage Mutant Ninja Turtles.
Flying Bark Productions, I can imagine doing a Sonic cartoon, but it depends on the team behind it. I'd much rather have a Sonic cartoon in style of Monkie Kid or Moongirl than 100% Wolf or FriendSpace.
Plus, it all comes down to who is producing it, so even with a quality animation studio, it might end up rubbish.
If I had to choose, I would say... the OK K.O. episode "Let's Meet Sonic" getting its own spin-off series. The crew behind that episode clearly knew what they were doing.
