Glock 42 has been a big hit and GlockStore's Lenny Magill mention in this video that Glock is working on a single-stack 9mm - around 1:20
When G42 came out GNB wondered if it was a bit of test bed for a single-stack 9mm and the rumor just doesn't seem to die. It would make sense from sales perspective as many G42 has been sold and now people will buy the long-awaited single-stack 9mm version.
