Probably not that big on the priority list right now. She's probably just doing the bare minimum, final stretch of her days as preggo after all. She's even dropped coloring it, going back to her natural black.
2 months for the baby to plop, one extra year for her body to go back to the old design provided she works out. You could be waiting 1 year and change, possibly more. If it consoles you, she's gonna release unreleased old content she filmed after she spawns the kid for the first, I'd speculate, 6 months.
