Patch dates are logical and not magical ; they do it in order not to screw with content they just relaesed.

Relic patch usually happened around the time you could get your tome weapon, which is around next week, and they have this shift so that Exprimal weap and crafted weap are not obsolete day 1.

I'm worried as well they might be a bit late on usual schedule, game starts to feel lacking fresh blood, relic story should help avoid and be around soon.
