Isn't he getting a movie in 2020?

Well we see the Mandalorian symbol along with quite a few others hanging over the bar in the movie. **** is probably being the Mandalore and gathering up all the ************ into a proper fighting force again who will probably go help the resistance

And since the clone wars is canon, that means all of mandalore is canon.

it is still canon he survived
we just dont know what he did after Ep 6

Not currently, the Legends canon on the other hand..

this is after the reboot of the canon

"If it comes from George then it’s true!"

According to wookiepedia, his last canon appearance was falling into the Sarlac. I'd love to believe he's still alive, and would love seeing the Slave II in action, but "George said so" doesn't strike me as credible anymore as it's Disneys say not his.

I'd pay more attention to the movie and advertising. Disney likes to be subtle and drop hints. Pixar even more so, but that's a studio far far away.

specifcally the behind the scenes section

Wookieepedia is where I also got this from

"However, on July 16, 2014, Star Wars author and historian Jonathan W. Rinzler stated in a Reddit AMA that Lucas has said that Boba survived the sarlacc,[30] though this has yet to appear in official new canon media. "

Wow, I read up to his personality, not expecting something like that to come afterward.
I'm 100% okay with this, so yeah, I might not have gotten to see the war of Mon Cal, or the Bacta wars, but Slave II hopefully!

Wait didn't his head got chopped off?

Jango Fett got his head cut off by Mace windu.
Boba Fett got knocked into the sarlac pitt by blind Han solo.

that's nines, and nines is a ginger. Fett's a kiwi.

but he would be old as **** , we need his grand neice to be the new bounty hunter but she is 10 so she is called lolita-fett
