Hi. I have not taken delivery nor received an email from them yet about locking config. I'm an August 2019 reservation holder. Adventure, FG, BM, 20" ATs, nothing out of the ordinary. I live right next to the SF deliver center in Burlingame. I'm in the same boat as you. Best of luck to both of us!
I don't like to be cynical, but at this point, I believe absolutely nothing CS or Guides say. Based on past experience, more often than not, what they say does not happen.
I went to the Sonoma event and test drove an R1T. It was incredible. I'm an R1S reservation holder since August 2019. I didn't go with launch edition because I'm waiting for the max pack.
After my test drive I was able to talk to a very knowledgeable product specialist for about 15 minutes...
