Have we talked about this? I am probably behind the times, as usual, but many of the most reliable American Girl leaks come from American Girl themselves...or at least from their trademarks. They have been known, of course, to trademark names that don't get used, however usually if there is a first and last name listed we can assume that we will see that character from AG at some point in the future.
Back in December of 2016 American Girl entered a trademark for the name Luciana Vega, which is pretty exciting, especially if you are of the mindset that AG is in desperate need of a more diverse pallet of dolls.
American girl has gone on record saying that they have no plans to end the Girl of the Year line, though we all know how much that means when you're talking about AG. (they were denying the retirement of the Bitty Twins as little as 3 days before they were pulled from the shelves) BUT if this is true it could mean that Luciana will be the GOTY for 2018. A part of me very much doubts this though, since it would mean two dolls of color (DOC) in a row for the GOTY line. Given AG's track record I would believe that only after seeing it...and possibly not even then.
Luciana could also very easily be the next character in their Contemporary line, a line of modern day dolls with stories that will kick off with the release of Tenney Grant in about 2 weeks. In that case I would expect to see her sometime in 2018. I doubt it would be earlier since there are expected to be at least five dolls already releasing in 2017.
That's right. Five. In addition to Gabriela (2017's GOTY) and Tenney AG is also releasing Logan Everett and the BeForever version of Felicity Merriman this year. The rumor mill also just went crazy with the report that a new BeForever character will be releasing sometime in August 2017. While it is possible that this BeForever character could wind up being Luciana herself, most believe that it will be the mysterious Nanea Mitchell, who was trademarked back in July of 2016. With all of these releases, it seems unlikely that AG would throw yet another doll into the 2017 mix, though their business choices lately have been questionable at best, so who knows? Despite how I feel about AGs recent decisions, I still don't expect to see Luciana until sometime in 2018, be that in GOTY, Contemporary, or BeForever form.
I will, of course, update with any information I manage to dig up.
