Lack of guild content has been one of the issues plaguing the game since launch.

I believe Yoshida said something like he does not want people who are not in guilds to be left out or something along those lines. It was said many years ago when people were complaining about it.

The lack of guild content is why most guilds are 6-10 ppl in this game and everyone does content in cross world statics and stuff. People just use Guilds as glorified chat channels more or less. Guilds in FFXIV are only for the social aspect, which in my opinion is completely missing the point of a guild.

I do not see this changing it has been a core philosophy since the launch of ARR. As for updates, I expect some more vanity stuff maby or some housing updates. Nothing that ties into battle content though.
