So, the Producer indicated that a feature they announced months ago was actually going live in a future patch and people are complaining the announcement should have included more than they promised?

Or is the OP's complaint due to the fact that they don't speak Japanese and someone else with an unknown agenda provided a translation that may or may not have been on-the-spot?

As always, humor/sarcasm/irony/whatever do not translate well and are misinterpreted in the oddest ways by people who read a translation of what was actually said without actual context. It's a Live Letter, meaning that it isn't explicitly scripted for the World Audience to incorporate nuance.
