It could get pushed back to Dec 2018 and move Mary Poppins Returns because no one gives a crap about that but will still probably give it billions of dollars anyway.
FTFY
After just now discovering that Beauty and the Beast is the highest grossing movie of 2017 here in the States - and by a significant margin over Guardians vol 2 and Wonder Woman - yup, I’d believe it.
Since this is one of the standalones, Disney probably doesn’t care about placing it only three weeks after the next Avengers movie. Similarly, they probably didn’t care about placing Guardians vol 2 - technically also a “standalone” within the Marvel franchise - only three weeks before the original placeholder date for Episode VIII.
