They said in the LB's announcement they'd give more info about it soon. Don't know why people are asking all the time, the first one was in September. Maybe it'll be sooner this time, but I'd recommend some more patience.
It probably won't be any time soon that they'll release them. But they also need to make normal Veronica playable from the story, otherwise it'd be weird to fight Veronica with Veronica (CYL variant)
