Alphascape Savage weekly loot restrictions are expected to unlock in patch 4.56, but some people are predicting that echo will come at the same time (since this is what occurred in the final raid tier of Heavensward).

For Sigmascape Savage, it looks like loot was unlocked in patch 4.36, but echo wasn't implemented until patch 4.41. There is a confirmed patch 4.57 (world visit system) so I'm wondering if maybe SE will implement Alphascape Savage echo at that time.

Does anyone have any definitive information on whether Alphascape Savage echo will be included in patch 4.56?
