AMD has seemingly confirmed that there will be more than just the fabled 8-core, 16-thread Ryzen CPUs we've only as of yet seen presented by the company. Come the expected Ryzen launch before the end of Q1 (which means, before the end of March), we should see more Ryzen CPUs than only 8-core solutions, though AMD still hasn't revealed exactly the core-count/configurations of the other CPUs on their product stack. Theoretically, AMD could follow the Intel path of simply disabling SMT (Simultaneous Multi-Threading, AMD's equivalent to Intel's Hyper Threading) and thus crafting another product, though this is pure speculation on my part. Whether or not AMD will include 4-core or 6-core CPUs on their product stack as well is as of now an unconfirmed, educated guess.
Additionally, in an interview with PCWorld, AMD's Jim Anderson, senior vice president and general manager of AMD's Computing and Graphics business, said the company are "(...) not going to do a paper launch (...) We've done that before. We're not going to mess with it". AMD's Rob Hallock further shed some light on the "Q1" timeline of Ryzen's launch: "When companies say first quarter or first half, people assume that means the very end of that time frame," Hallock said. "The very last day of Q1 is not our trajectory."

Oh, and as a coup-de-grace (pardon my french, artistic liberty here), AMD has seemingly confirmed that all Ryzen CPUs will be unlocked and overclockable - though while overclocking is supported with every Ryzen processor, only the more enthusiast-focused AM4 boards with X300, X370, and B350 chipsets will actually be able to crank those chips to... your particular choice of multiplier.
