Yeah. I still don't think SL is gonna get a 9.3 (It maybe will, but still), but the Delays aren't a WoW only thing. Even Nintendo's been crazy with Delays. Breath of the Wild 2 is taking a very long time to release, but no one cares about the delay, cause that's not an MMO, so people don't feel as rushed or as bored, or anything like that.
FFXIV's got some crazy things too going on, but to FF's credit, their devs are VERY passionate, as to do multiple games at a time. From the XIV MMO, to FF Origins that was apparently announced...
It's crazy. Not to promote the game or anything like that, but their situation is a little different from everyone elses.
