I can't vouch for it 100% yet, but something that's brand new and showing in Japan right now is Durarara, which you can watch free and legally on the site where I just linked (if you live in North America). It's from the same creative team behind Baccano! (which if you haven't seen I will also recommend--you can buy the entire series right now or watch it on Funimation/Youtube), so it has that pedigree behind it at least. The catch with the Durarara streaming is that you only get the new episode a week after it airs with the 'free' account, and you can't watch it in 720p. Paid members get to watch it one hour after it is broadcast. So you may resort to going back to good ol' fansubs for it, but Crunchyroll has become a pretty good place to check things out.

I will also recommend Cross Game, which you can't watch quite as easily as Durarara or Baccano as no one has licensed it or is legally streaming it. It is currently my favourite 'currently airing' show. Yeah it's a baseball anime, but seriously, give it a shot. And try to get past the first episode, I promise the rest of the show is not quite like that (you'll understand when you see).

None of these shows are "serious" if you are talking stuff like Akira or Ghost in the Shell, but they are definitely not pedestrian shows for Children. Cross Game in particular is quite witty.
