Production Weekly gives me the appearance of it being far superior to IMDb. I don't know if P.W.'s verification process is more stringent than IMDb's but it looks like it is. Again I don't know what the professional reputation P.W. has in the movie industry but at least perhaps the update was of some significance and an accurate one.
Well, for what it's worth, the last time Production Weekly listed the Depp/DS film, they said the film is about a dream in which a girl takes a long train ride to visit a large mansion instead of being based on DC's dream. So, simply going by that, I wouldn't necessarily say
everything they publish is accurate.
Whoever came up with that description definitely screwed up a bit.
They also listed Tim Burton as director, which is something TPTB are still refusing to confirm or deny, so chances are very good that the info in the listing didn't come directly from TPTB.
