Sure there was. Elon tweeted this on Fri, Dec 10:
So if 10.7 ships any time this weekend, its right to time. But honestly, the 'next beta' doesn't mean much.
The REAL question folks should be asking is "When does DOJO come online?" It's been about a year, could be anytime now. THEN, we'll see an order of magnitude increase in NN training productivity, and a consequent increase in the number of problems the FSD team can solve per week/iteration.
The lack of DOJO is the single most critical barrier stopping the merger into the 'single-stack' for Nav-on-Autopilot (Highway FSD) and FSD Beta: Tesla simply does not have the compute necessary to add in all the baggage of the N.O.AP data set into the already bulky beta data.
When Tesla launchs DOJO, that will change quickly.
Cheers!
