In an interview with EU Content Creators, Ion Hazzikostas revealed that the Swift Spectral Tiger is unlikely to return via promotions. In the interview, Ion Hazzikostas has stated that he wouldn't expect all of the TCG Mounts to show up back from drops.
However, these TCG items were always promotional items and the recent promotion are old items becoming available to players who weren't around back then or who didn't have TCG available in their regions, as that didn't feel fair. It didn't feel right that the only way to get these collectables previously was to go to a 3rd party site and buy them for a lot of money.
Ion Hazzikostas called out the Reins of the Swift Spectral Tiger by name and mentioned that there are a couple that they are going to take extreme care with, the Reins of the Swift Spectral Tiger included. He wouldn't expect this mount to drop randomly through some promotion.
Ion personally would be surprised to see that coming back in any form, but if if it did show back up, they would think very very very very carefully about it as they know what players have put into getting them and how treasured they are and taking that away overnight would be wrong.
