Ripping sprite animations from official websites

[Fawfulthegreat64]

I want to rip and sheet a character animation from the official website for the Thousand-Year Door remake. I've seen some supplemental materials from the web ripped and submitted under a separate "game" on the site before, so would that be acceptable here? And if I can, would fact that the website is for an upcoming game be an issue for rips from the website?
