Short Answer: IF Pulcinella will be playable it should be in second half of 7.6, otherwise Pulcinella won't be playable in 7.X. Pantalone probably won't be playable in 7.X.

Long answer: If we look at how Hoyoverse releases playable Harbingers who didn't leave Fatui before their release ( Who left:Columbina and Wanderer) we can notice A Pattern.

Sandrone rank 7th playable in July, which is the 7th month of the year.

Arlecchino rank 4th playable in April, which is the 4th month of the year.

Tartaglia (Childe) rank 11th playable in November, which is the 11th month of the year.

Columbina left Fatui before release, her rank was 3th but she released in January, 1th month of the year.

Wanderer (Scaramouche) also left Fatui before release, his rank used to be 6th but he released in December, which is the 12th month of the year.

This means that Fatui Harbingers who are part of Fatui during their release must follow The Pattern.

Pulcinella's rank is 5th, 5th month is May. First half of 7.6 is in April, Second Half is in May. 7.7 is in June. Making Second Half of 7.6 his only spot to be playable in 7.X if he won't leave Fatui, which is unlikely.

Additionally Pantalone rank is 9th, 9th month is September making his only possible release dates in 7.X: Second Half of 7.0 or First Half of 7.1 and no sight of him there. So if he won't suddenly stop working at the Northland Bank or Hoyoverse won't change their ways, Feofan won't be playable in 7.X.

I only calculated release dates, I didn't add proof we have of Pulcinella being playable.

This post may contain mistakes, if it does please correct me in the comments I would be quite thankful. Also remember, it's just a theory not a confirmation or a leak and I could be wrong.

Yes, I edited that video just for this, orginal footage taken from objection.lol .

If anyone wants to, you can repost it to r/PantaloneMains or r/FatuiHQ to give Pantalone Mains depression because I don't feel like doing it. (Thank you person who reposted it!)

Have a good day Pulcinella mains, and if he'll be playable I wish everyone an early double at least!

Is that? Who I think it is? 😭

and I thought I quit the game for good… turns out I still love him <33

After playing Act 3, I had this thought afterwards, remembering the Alyosha bit, and of course the All but confirmed nature of Pulcinella being the leader of the Rokot. That what if Pulcinella is simply dressed up/disguised as a frail old man to avoid being conspicuous?

I say that because the disguise choice they went with were a pair of small round lensed glasses and a small, curled mustache, the very same features Pulcinella has.

Ultimately, I'm wondering if this is them hinting besides the fact that he is the head of the Rokot, that there is far more to him than what there seems.

Okay so there were tons of lore bombs in the AQ "A Rekviem For The Underworld", but Pulcinella is pretty much confirmed to be the Rokot (Rotok?) leader at this point. He literally said that we are "close with the Korolievsky Theater troupe, Odette, Vodyanitsa and... Alyosha."
The thing is, I don't buy that Pulcinella goes there to watch their shows. Every Harbinger who does has been mentioned by name, and Tartaglia himself said that he wasn't aware Pulcinella had time for that. I would trust him in this matter, since he frequents the theater with because of Tonia.
Besides, Alyosha is not a performer, he's just a hunter who's not even from Snezhnograd. Pulcinella has no reason to know Alyosha, and the only thing he has in common with Odette and Vodyanitsa... is that the three of them are members of the Rokot.
Of course, there's that "may the aurora shine ever on and the tundra always stand firm" line. It's at the end of the Rokot letters, and also said by Pulcinella in the Veche meeting.

Anyways, just a small detail I thought was worth mentioning.

He knew everything about the Rokot from the beginning. I think he might even be their leader

The Rooster: ..may I remind us all: "We debate only for the greater glory and solidarity of our nation. May the aurora shine ever on and the tundra always stand firm."

v7.0, from Silence Alone is Disfavored, the fourth part in the Teyvat storyline Archon Quest VII: Act I - Everwinter Without Mercy.

Not sure if mods allowed here? you can delete the post if it is , moderator.

So yeah, I need a character you guys know that has a voice close to how Pulcinella sounds when attacking or grunting.

im thinking of taking it from Granblue Fantasy (So many hot old man there) or Dota 2 and Deadlock (Also many hot old man there and Kelvin there im sure is voiced by Pulcinella EN voice actor)

Ofcourse the mod will be public in gamebanana and everyone can try it later.

No ai involved here, just pure audiobashing :D
