According to the news item by GI staff writer and Lara Croft fan/cosplayer Meagan VanBurkleo, the next Tomb Raider will indeed be an updated origin story.
"Rebooting the Tomb Raider franchise through an origin story wasn't so much a choice as an act of necessity, according to Crystal Dynamics. Drastic measures were needed. To build an entirely fresh Lara—a culturally relevant hero worth of the attention that once came so effortlessly—they must break her first. In this new adventure—simply titled Tomb Raider—a younger and inexperienced Lara Croft must endure both physical and emotional trauma to survive."
