According to Cartoon Network's official site, Sonic Boom will premiere next week Nov 8th at 7am eastern. The pilot will be "Sidekick/Can an Evil Genius Crash on Your Couch for a Few Weeks"
Now this may seem concerning. You may be thinking no sane person on this earth will get up at 7 am. Recall though that the target demographic is for kids ages 6-11 and 7 am for them isn't that bad... unless it's central time where it would then be at 6 am. Then I am sorry for them. I recall Sonic Underground being on at 6 am. Not fun.
