I think I'll be happy with whatever they give us, as long as the animation for the mount is done well and the artwork doesn't look odd.
I'm confused by the "as long as it doesn't disappear in combat" comments. In EQ2 you can choose to fight on your mount, turn it off for combat or hide all. I always thought it would have added a "coolness" factor if the mounts actually fought with you. Rearing up and pawing at the enemy instead of leisurely chewing grass while the battle raged on around them. Well trained, those mounts. LOL.
What I don't want to see is the implementation of achronistic mounts. Motorcycles, cars, trains.. chocobos... those kinds of things.
Hoverpads would be cool and maybe mechanical steeds would be okay. But I hope they steer clear from the realm of silly.
