TCEC VSOB 21, CCC C960 Blitz Championship : Both Underway

The previous post on our two ongoing, world class, engine vs engine competitions, TCEC VSOB 21, CCC Blitz 2021 : Both Still Underway (September 2021), can be summarized as follows:-

TCEC: The site is still running 'VSOB 21'. The schedule says it will run until the first week in October. • CCC: The six top engines in the 'Blitz Championship 2021' qualified into the semifinals, where the two top engines qualified into the finals, which was convincingly won by Stockfish over Lc0.

That post paralleled the post before that. What can be said about the current status of the two competitions?

TCEC: The summary of the previous post accurately describes the current situation. Given that the first 'VSOB 21' game was played on 28 August, the event will finally have run for more than five weeks. I mentioned the previous VSOB (numbered 'VSOB 20', i.e. 'Viewer Submitted Openings Bonus') in TCEC 'VSOB'; CCC 'ECO Mega-Matches' (April 2021). It ran for less than five days.

What's next? The TCEC crystal ball says, '!Cup9', with the further info:-

Plans to increase the number of participants from 32 to all(?) participants in the Leagues. This change would need testing (GUI brackets and byes).

The TCEC cup events use a knockout format based on mini-matches. For the previous cup event, see TCEC Cup 8, CCC Rapid 2021 : Semifinals Both Underway (March 2021).

CCC: The CCC is currently running a 'Chess960 Blitz Championship' with 12 engines in a multi-round all-play-all format. The event will continue until the end of next week, after which the CCC '!next' command says, 'Chess960 Blitz Semifinals'. That is the first update to the '!next' command since the end of April. Can we expect more information about the format of the event? Lesser miracles have been known to happen.
