looks like May to me, but still hopeful for April:
"Production has wrapped up and your Model X has just moved into the factory inspection phase of the build process. This is a very robust series of tests. We are hyper focused on quality and have incorporated additional layers to the inspection with new owner feedback. While we do not have an average time for how long the inspection takes, I do anticipate that we are a couple of weeks away from delivery. As soon as the inspections complete, we will be able to schedule your appointment with us here at the factory!"
