So, with the real-money items be available permanently (ie. Sleipnir)?

In all honestly, I don't generally like microtransactions, but since I'm a fairly inconsistent player anyways, I figure I'll probably wind up getting Sleipnir whenever I start my new Dark Knight character in Heavensward (personal choice, obviously; I just don't want my Dark Knight to be a Miqo'te, but will still keep this character, too).

I wanted to ask in advance, though, if there's any chance these items will be removed at any point? I know some games -- usually Free-to-Play -- will only offer items for a short time before retiring them, so if that's the case, I might apt to purchase it now.

Sleipnir is a fatty, PVP Warsteeds are better

I'm hoping it will be the mount they talked about that you can get as an achievement for getting all of the ex mounts. I would be ok with that. They are providing ways to obtain the cash shop dyes in game, so there is a chance that they will let us obtain the mount for free in game at a later time.
