Why was the second Pillar Talk video not about Pillars? Is this an indicator that those Pillars have been abandoned and replaced by other goals?
TL;DRNo, the Pillars haven't been abandoned; only two episodes exist, the second used the format to discuss staggered development, and Pillar Talk will continue to cover Pillar issues with Pillar directors.
Absolutely not. They've only done two episodes of Pillar Talk, so they're still exploring the format and all of the different areas that they can touch on with that format. For the second episode Erin was visiting the LA studio, and since they had already moved towards the new Staggered Development initiative, they thought it was a good opportunity to have him talk about that candidly with John and Eric, and attempt to shed some light on why they're doing a lot of things that they're covering in this episode of SCL. In the future, Pillar Talk will continue to address Pillar issues with Pillar directors. If the show was only going to be about stuff that was specific to a patch, they probably would have called it Patch Talk, so they're going to continue to iterate with Pillar Talk as a format, just as they do with anything else.
