Roberto Orci has been interviewed by IGN regarding the next Transformers animated series.  Roberto confirmed that both he and Alex Kurtzman will be returning to produce the new series and but also has started that it will be more kid-friendly and less intense than Transformers Prime but that they would welcome back Peter Cullen and Frank Welker to the show.

It’s not really a reboot, it’s sort of a continuation of it [Transformers Prime] in a tonally different form. We want to make sure we’re servicing the right audiences. We got to do a very adult version of Transformers that you just saw in this cartoon, a very sophisticated one, and we also want to make sure we don’t leave other kids behind, who love Transformers too and don’t want to be as scared as Transformers Prime could make you, that kind of thing. So we’re going to have a good parallel series that is connected, but it’s a little more friendly to the family.

When asked whether the show will be a "kids-only affair", Roberto replied:

I would say that clever wit always makes it something more adult. I think the look of it, you may find, is more kid-friendly. But we certainly don’t intend to be any less entertaining or any less Transformers. But there is a little bit of truth to that. I won’t deny that also, yes, we’re trying to make sure that younger kids who really love Transformers aren’t put off by its intensity.
