I heard back today. Steve actually had emailed me after my order because there was a glitch in the system that forced people to choose the black paint option and he wanted to ensure I wanted that. I think they might have just been busy contacting customers who placed orders during that time period.
Although he couldn't give an ETA, he was able to confirm I'm receiving the new barrel profile as opposed to the old. Still wondering what the differences are between the old and new?
