Fat chance.. i doubt they'd change the style of the show which means Caesar will be fucking and gore'ing his way through his show (or he'll only do the fucking and leave the blood to someone else).
It's the appeal and style of the show.. the first season was awesome due to íts characters and overall story. The sex and violence was not really needed to make an interesting show but it sure draws the attention when you market it that way.
I don't think well get something akin to Rome.. they'll bend the Caesar character a bit to emphasize the violence in his life and introduce some hot women so they can fill the tits quota.
I gave up on Spartacus after Whitfield died.. the new guy is ok but he never really clicked for me. Doubt i'll watch Caesar.
