Paizo posted a link to a good & extensive interview with Starfinder's Creative Director, James Sutter:

It still looks to me like Starfinder's going to be different enough in detail that Hero Lab will need to treat it as a new system, much like the 2nd & 3rd editions of M&M and the 4th & 5th editions of Shadowrun are separate systems (and for that matter, d20 and Pathfinder). The only specific point of compatibility that is ever mentioned is the ability to use Pathfinder Monsters as Starfinder Monsters, and it wouldn't surprise me if that ends up getting done in Hero Lab by an explicit "Import Monster from Pathfinder" function, if it's supported in HL at all. Even the list of Core Classes is different in Starfinder, even if several of them have obvious parallels in Pathfinder.
