The movie will be produced by Hannover House (Twelve) and Red Bear Entertainment and they're targeting a PG-13 rating, which is really no different from the last couple Terminator movies or the TV series. The press release announcing the project does still mention plans to minimize the violence, however, to achieve the classification. No plot has been revealed, obviously, nor do we know when it'll make its way to theaters. Production is expected to begin in January.
I guess it was only a matter of time before there was an animated Terminator. All the major franchises get into the medium at some point. Actually, I'm surprised there was never a cartoon series, though I think we can now anticipate such a spin-off if this is successful -- or maybe even if it isn't (ahem, Clone Wars). Let's hope Hannover uses the following animation as inspiration for what direction to go in:
