"In development" announcements have recently become popular with camera and lens manufacturers as the way to reassure fans that they're really working on something great after long months (or years) of silence. But Ricoh's announcement that a GR III -- the update to its GR II fixed-focal-length, APS-C compact -- is "currently under development" with few details seems a little desperate for Photokina 2018, especially since it's not slated to ship until early 2019.
Look for it in 2019.
