Same day as the K-5 II, according to the DPR database. So probably not a good guide to future Pentax announcements.
Overall, K-3 to K-5 was a significant step up in tech - in particular sensor size, 86k metering chip, and AF. A real K-3 II replacement should reflect a similar scale of hardware upgrade.
My guess would be to expect one or two significant 'headline' features - eg lots more AF points, higher resolution and smarter metering sensor (inc real face detection in PDAF?), 4K video etc - plus lots of incremental feature upgrades.
