I have been listening to a podcast of a Starfinder "Dead Suns" game lately.
It has got me to think about purchasing Starfinder.
Then Pathfinder 2E just came out.
And reading through the forum, it seems to be the general opinion that Starfinder was the "prototype" for Pathfinder 2E.
I do not see any news of a Starfinder 2e being worked on or released, but one would be expected.
I would be very upset if I bought half a dozen books now and 2-4 months down the road, a Starfinder 2e was announced or scheduled to be released.
