Well remember, not that many people are into Ben 10 in US standards, because fans gave up around half way through Ultimate Alien during Season 2. Another group left Ben 10 because of Omniverse being made, because most people couldn't stand Gwevin being lowered to as recurring roles, and also because of the animation style.
But IMO, I liked the idea Rook happened, and the animation style to me makes Ben 10 look cleaner than UAF.
ANYWAY, Galactic Kids Next Door does have way more hype than Ben 10, because KND is something fans actually group up with 10 years ago, and bringing it back would spike Cartoon Network's ratings, but I think the reason the didn't do this is because their not into having action shows on their network, since only a few shows are airing on CN right now while the rest of it is being burnt off.
But I hope CN does take consideration into allowing Kids Next Door to come back, but I don't think the petitions will do any good, I mean look at Tron Uprising or Young Justice or even Sym-Bionic Titan. A lot of people back in 2011-2013 got really screwed over because of the loss of those shows and others, and that was when CN will still being appreciated, now when you look at it, it's all wonky and screwed over as to say, just go watch our shows online, we don't care about what you want.
The only thing Cartoon Network has done right since then is bringing back Toonami, and that was for Adult Swim.
But to go back on topic, the Ben 10 reboot, I'm not sure how well that'll do, in North America it'll just be streamed all over the internet, because its airing in other countries first. And even if NA gets it before them, which is highly doubtful, it'll be burnt off at 6am, or at 3pm, because that's what Cartoon Network's doing now adays, they can't air anything right.
I think once we get an official teaser or trailer, or anything thus-far big & new, this forum might be as active again as it was back in Omniverse, or even bigger. I guess we just gotta wait and see.
