Their message is confusing. They had just annouced PowerPC based SoCs using the 476 core from IBM and now ARM A15 based SoCs less than a year later. Unless they had multiple teams working in parallel this sounds like vapor-ware.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
