Summary:

The most recent prototype of Starship is expected to get tested in early April

Main Question or Discussion Point

SpaceX loves confusing numbering schemes, but so far we have seen five relevant test articles: Starhopper ("water tank") made a 150 m flight, Mk1 was the first full-scale prototype but got destroyed in a pressure test, Mk3=SN1 got destroyed in a pressure test, SN2 was a tank test only (successful), now SN3 is being prepared as full-scale prototype and it is expected to make shorter flights later.

Yesterday the tank section was finished (image). They got a one-hour road closure on Friday to transport SN3 to the test/launch site, and a full-day road closure Wednesday April 1 (with backup dates the following days). It is expected that they will do pressure tests with the tanks, with a static fire planned for later. The payload section and nose cone are expected to join the tank section then, followed by a flight test.
In parallel to these activities SpaceX is preparing parts for the successor, SN4. It will be built for longer, high-altitude flights. It will also need the external fins for that.

Edit: They are faster than I expected. The road closures are for a static fire on April 1 and a 150 meter hop on April 6 (source).
