Oh yeah, people are still talking about this, and it seems that it MAY be true, well, according to Meet the Movie Press. They quoted that it's:
Not only still the case – but it’s a “done deal”.
There's still no director for the movie, however, let alone Blunt already confirmed to BE CAPTAIN MARVEL?!
Blunt HERSELF is completely aware of these rumors about her being Captain Marvel, she's spoken about the topic in the past:
‘Oh! No one’s offered me that officially, so it’s…v ery unofficial,’ Emily said, ‘I think it’s fan-casting, which is always very nice. But nothing official has been offered, for sure.' - metro.co.uk
Blunt had made some murmurs about the project saying that nothing official had been offered (other than two roles she had to turn down), but now Movie Web and Meet The Movie Press are citing that mysterious “sources” have confirmed Blunt’s name with the role. - UPROXX

Another rumor that speculated around, according to 'Pedestrian.tv', claim that a rumor was spread that Angelina Jolie was offered $20m to direct this movie, although it apparently didn't work out.
Well, even if this is JUST a rumor, who WOULDN'T want Emily Blunt as our new 'Captain Marvel'?
