From reading some threads, it seems that U20 was scheduled for Nov. 12 and Massively let it leak.
This seems odd to me, because usually they've advertised in advance of when Updates are coming. However, after the big noise we made about the Saga Commendations, perhaps they just wanted to sneak this one by us?
If we are actually going to get the Raiders Box, then this was our last weekend to get our toons through raids or TR to qualify for it. Keep in mind that Chronoscope and Tempest's Spine don't qualify.
Anyone reading this should use what's left of the day to qualify or help friends and guildies qualify.
