I don't know if it specifically got mentioned in this thread but there's a 4 entry gap between Brook and Roger in the new Vivre Card Databook. I assume the 4 missing entries are for the Strawhat crew.
#1 Luffy
#2 Zoro
….
#9 Brook
#10 ????
#11 ????
#12 ????
#13 ????
#14 Roger
#10 is of course Jinbe and he's been teased as such in the cover story.
My own personal theory is that #13 is the ship/klabautermann.
The ship has a giant #13 on it. And based on the early crew art there was a midget shipwright that looks suspiciously similar to the Klabautermann.
Now I know that there'll be some debate whether Going Merry AND Sunny will get their own numbers but I don't think this is the case. Didn't Franky state that the spirit of Merry lives on in Sunny? And although not canon, Episode of Merry spelled it out that Merry and Sunny are inhabited by the same entity. The anime does fact check somethings with Oda, so I don't really have any reason to not believe that the anime in this instance. I know some things have been revealed by the anime before confirmed in the manga or SBS, such as Charlotte Kato being a member of the Big Mom family and not a homie like most people were assuming. So it only makes sense for the Klabautermann, Merry, and Sunny to have one entry (as #13).
The leaves #11 and #12 for new crew members.
Someone else pointed this out to me once that the name for the crew in Japanese is Mugiwara no Ichimi which could also be some wordplay which Oda loves. Ichimi = Ichi, Mi or 1, 3. We've already seen Oda use wordplay with the Strawhat's devil fruit numbers as well as the name of the ship, so I don't really take it as a stretch if Oda's using some wordplay again.

Oh yeah and I think Carrot is one of the 2 new members after Jinbe.
People are only ardently opposed to her because they think there's only 1 member after Jinbe. If the crew ends up being completed by end of Wano arc like most people are predicting then Carrot will probably end up being one of the characters since she'll have been with us for so long.
