Ninjago shows us that action shows can do really well with no big competition. It seems like they always want to use the actions shows to go against Nick and Disneys strongest times. I'm sure ThunderCats and DC Nation could do very well on Thursday night. Star Wars will hopefully stay on weekday nights, because I think that's much more fitting to it.
I'm kinda against having premieres before 7:30pm, though I guess 7pm would work too. We can't touch Monday night, because that's working out too well for comedy. The same kinda goes for tuesday night. I think Ben 10 would work well after Ninjago, they return at about the same time right?
Pokemon and Beyblade are weekend shows, and I think they should continue to be so, also Redakai I guess.
So if we have lets say Gumball, AT, RS and MAD on monday. JT, TD, LU, Scooby and TLTS tueday (they wont all be on at the same time anyways). Then we could have Ben 10, Ninjago, Star Wars and ThunderCats Wedensday, though I'm not sure about the order, and DC Nation thursday. With room for more programs (New Shows, Batman, Teen Titans, Justice League etc). Cartoon Planet on Friday could get another hour too.
