FYI, I have a Plaid S on order and when the CSRs called me last week to finish my profile I asked them if they can guarantee that my Plaid will have the updated headlights/tailights/badging. They said no, they can't guarantee it right now. So I told them to delay my delivery.
Based on the news I've seen so far although all new LR orders will be updated... it sounds like they still have inventory of Plaid Ss that don't have the updates. Until I hear otherwise I'm going to keep delaying.
