I've taken the plunge and ordered a MYLR in White/Black and 20s when the delivery EDD was May (I knew this wasn't going to be the case). This then unsurprisingly changed to July when I spoke to Tesla, and now I just checked my account and it's been amended to June 14-30th.
Looking like another end-of-quarter push.
Same spec as me. I ordered on 1st April and was given a June date. After a few days my EDD moved forward to May 21 - June 18 and it has remained there for the last 2 weeks.
