This is a complete list of everything they teased about RWBY and gen:LOCK at New York Comic Con 2018 as far as what the stream showed. They cut the stream a bunch, but they also talked about what they showed so we have a good idea of what they cut the stream for.
RWBY
- RWBY is in Shonen Jump with stories of Volumes 1 and 2. It will be simultaneously distributed in Japanese and English.
- They showed a promo of some sort before the show.
- Miles loved a funny interaction between Fox and Ruby in After the Fall.
- Qrow figurine merchandise is coming soon.
- They showed some of the RWBY premiere. It was approximately 8 minutes 30 seconds long based on how long the stream was cut for.
- It had music in it. I don't think it was the opening theme. I think it was a new song.
- New fight scene was in it and probably had the Manticore Grimm. Probably also had the new music alongside it.
- Also Weiss had a scarf and tights in it, as they teased the destination was "chilly". But also said they couldn't do too much of a costume change. (Maybe because it's not too chilly where they are but once they get to Atlas they will wear warmer stuff.)
- Argus is a new city in the show.
- Arryn said she's excited to see Neptune, so he's coming up.
- Kara said something about a train but not the one from V2. The Argus Limited from the Fathom synopsis is probably a train.
- Miles said "a lot of longstanding questions about a lot of people will finally be answered" (being vague about many will assume is a Bmblb tease)
- Manticore and a new Sphinx Grimm exists.
gen:LOCK
- Chad James voices Jody. Stylish guy with a goatee, a part of the Vaguard mech force. Gray plays Leon, a part of it too. Miranda is in it too.
- Migas, Miles' character, is an "engineer, videogame player and goofball." He is from South Texas (as in "southern Texas") and the story of his nickname embarrasses him.
- Razzle, Lindsay's character, is a member of Chase's Vanguard squadron
- Lindsay auditioned for Cammie, but her poor Scottish accent made Gray said "Lindsay, that was fun."
- They cut the stream to show what is probably the sizzle reel they show at conventions.
- They showed the poster for Season 1.
- RT partnered with DC comics, and RWBY and gen:LOCK are getting made into comics in some form in 2019, and then other RT properties will be made into comics later too.
- Part of episode one of gen:LOCK was shown. Based on how long the stream was cut for, it was approximately 6 minutes long.
- Julian Chase has a sister who was shown in it. No word or insinuation if she was younger or older but I think she was younger.
- There is a scene where Chase introduces his family to Miranda via VR.
- The Aether or Ether exists, and it's like the Matrix where you can do a full dive into it. It can also, however, integrate into the "real space" aka real life in a sort of augmented reality way.
- Blaine crushed his performance as Rob Sinclair.
- They cut the stream for a scene where the gen:LOCK six meet each other for the first time. It was approximately two minutes long.
- Arryn Zech auditioned for Val but she said her accent was worse than her audition for Cammie.
- Saturday, January 26, 2019 premiere date.
