Mount yes, they exist on the frontpage news. Wing, think of the Dragonlord wings but blue.
What are you talking about? Front page news? No pictures of the upcoming mount or wings or other cosmetics exist there, unless it's hidden in a non-obvious place (do you have an url you can link?). Why are you intentionally spreading false information? Why are you trying to confuse and frustrate other people like this?
Do you have screenshots you can share? Not just "think of this but different".
Do you have a picture to share that shows the green dragon mount (not just an image of a random green dragon)?
Do you have a picture of the dragon hatchling pet?
Do you have a picture of the Blue draconic wings (not just your imagination, some people struggle replacing colors in their mind alone. Aphantasia is a real thing)?
Do you have a picture of the Prismatic Dragon Outfit?
Do you have a picture (or better yet a video/clip) of the Dragon Path Aura Footprints (still images of the gold footprints did not do them justice with their shimmer)?
Do you have a picture of the Armor of the Cult of the Dragon (that the players are going to get, not a Cult of the Dragon NPC)?
I'm sure pictures exist somewhere with a dev (saved on one of their computers, or concept art only if the art team hasn't finished making an in game version yet), but that is not what the OP is asking (if it exists somewhere anywhere in any form atm), they are wanting to see what is actually going to be coming. See it. Not imagine it.
