It's come to the point these words and others don't have any meaning anymore. It's all muddled BS tossed around. Vintage used to actually mean something that was old in good condition same with the word 'Antique' which at one point meant something made by human hands not machine created. Eventually 'antique' included machine created but old usually 2 generations or older and now it just means whatever people want.
Same with 'theory' or 'speculation' which on YouTube means people ranting or pulling things out of their ass. Nintendo people I think are the blame for this due to Nintendo waiting so long to come out with BOTW2 and people started to toss shit around since we only got a 30 second teaser which people have turned into a half hour speculation when there really isn't anything concreate. They often repeat themselves like 5 different times thru the video.
The word 'Theory' and 'Speculation' used to be separate meanings but now are interchangeable and wrongly used in these types of videos about future games or game lore.
there doesn't seem to be anything here
