Quarterly earnings will be released April 22. My impression is that in recent years, such rumors tended to cluster around earnings reports (which largely haven't been great the last 2 years or so), presumably as distractions.
They don’t really need this though, every TSLA investor already louds that TSLA is not a car company - I think now it is no longer “Robo”taxi company either but humanoids-data-center-on-Jupiter-moon-mining company. Hence, absolutely no need for any EV announcements :)
