I don't know if a production test model will roll out, but I'd expect this to be a great time for them to put up the final CT renderings planner for production. The model S Plaid is obviously going to be the focus, but the CT will probably be there in some capacity.
I'm really hoping for an update on the CT, but surprised so few are looking at Semi. They've had multiple prototypes out for testing and talked about starting production this year also. But Tesla has a good problem. They have CT, Roadster, Semi and Model 2? in the pipeline and Everybody wants their choice to hurry up and get into production. If they don't release any info on CT on the 10th, they need to have some info by the time the Q2 call comes. That is where I expect to see more info on all that Tesla has going in their 5 ring circus.
