Thanks for the info. There is a Nikto-codex entry at the heavy armor-vendor nearby, too. Don't know if it is new, but I never saw it before.
Neither the Nikto or the Weequay codex entry are new truth be told. Same with the Trandoshan on Belsavis, even though before this update, you could only get the latter when killing a specific Elite.
Haven't checked yet if it works for every single one on Belsavis now.
Still no pictures on them though.
