An alleged animatic clip for S06E01 was posted on various channels including Youtube.

I saw it and it looks completely fake - quality isn't comparable, fonts are different, and many details don't match the usual techniques/standards the producers seem to follow.

Supposedly, it was also confirmed as fake on a (twitter?) post by one of the show producers.

Should be safe to watch for a laugh, but anyone wanting to be totally secure may want to still avoid it just in case.

Also, it was made to fit the real 20sec premiere preview, so it fits the setting and the places... Which means that seeing it may at least spoil the premiere settings.
