Leak for the Rugrats reboot:

The show takes place during modern day, and the original rugrats are all adults who have kids of their own. Pretty much every senior character are dead, but the adults now take their place. Spike is also dead, but Spiffy and Sparky are both older. The show focuses on Tommy and his wife Rachel's kid Louie and his baby friends going on adventures with their imagination. Stu Pickles is apparently also getting a new voice actor.
