okay, i did not come up with this theory but i can't find original posts about it so i decided it would be easier to recreate one.
Possible Release Timeline for Taylor's Version Re-Records
i'm confused and amused that people seem to be all worked up about figuring out the order of the re-records because she already told us on september 18, 2019:
(some folx theorize that that last pic, the greenish one from SNL, might represent Debut. that could be, but since it was posted much later, on october 7, and it doesn't have the same lyric-quote-caption pattern as the others, i'm not going discuss it here)
the colors are related to the original cover art for those albums and taylor herself confirmed that she used this color code to represent the albums with the rooms in the Lover music video. (looking back, we can also see it in the LWYMMD video!)
the captions for these four posts are quotes of lyrics from Lover, which this Rolling Stone photo shoot/article was promoting. people took note of the word count of the captions:
💛: "It's golden, like daylight" = 4 words
💙: "It's blue, the feeling I got" = 6 words
❤️: "I once believed love would be burning red" = 8 words
💜: "Threw out our cloaks and our daggers because it's morning now" = 11 words
people theorized that the word count represents the month that the re-recorded album would be released.
and she DID in fact release Fearless TV in April!
therefore, i think we can confidently conclude that we will get 1989 TV in June, Red TV in August, and Speak Now TV in November.
