There are still no word on plans for the WWE Divas Title at WrestleMania XXX. The original plan, before Naomi got injured, was for her to face AJ Lee in New Orleans. Naomi would likely have won the title as part of a storyline on the next season of Total Divas.
Naomi's injury and comeback can still play into Total Divas. After receiving word last week that she won't need surgery, there is still time to figure her into WrestleMania plans. She's estimated to be out of action for 4 to 6 weeks. She won't be able to appear on TV, unless she drives to RAW, because the pressure from a flight would be dangerous for her condition.
