Honestly, let SE make as much money as they can.

Thing is, they aren't assuming we want a vanity cash shop XD. Mog station was already suppose to be implemented to provide extra services for FF14, and like Yoshi said himself it takes drastic changes/planning to switch to a cash shop model. They are also even less likely to add one in when they can sell you something else and add a code for an "exclusive FF14 in-game item." Like they have with those minions.

"Welcome to the FINAL FANTASY XIV: Mog Station, the management page for all FINAL FANTASY XIV services!"

Yes, extra services like server transfers, name changes and the likes, not two full fledged retainers for 2$/month each. As I said in another place, even F2P games that -obviously- lack a sub to get money charge just once for extra inventory space. P2P games shouldn't even have to think about doing things like this one.
