Expecting a job tease, news about a stat squish or some other system changes; TP removal from skills was revealed at the first Fanfest for 4.0 and its outright removal was at 5.0's first they also detailed charge actions at that time. We'll probably also see a trailer and find out what the next limited job is, since they're creatures of habit and will absolutely release a new limited job in 5.5. Other than that? Who knows.

I mean, this is for PLLs. Which there is one immediately following the announcement showcase, so the showcase itself is for the "future" of FFXIV; as Yoshida has clarified numerous times since it was announced in November, rather than for the expansion we're currently in. People seem to forget the order for the events on the 5th was the Showcase > 14hr Broadcast > late night PLL > Continuation of broadcast. All we're missing out on is the 14hr thing, and need I remind people that the showcase was literally going to have a live audience that was specifically invite only.

All the PLL stuff was to come after that, not before, as the showcase itself was supposed to "clip" into the start of 14 hour stream.
