@RiotReinboom: Abyssal Rework Update and AP/MR items

I would like to ask the Balance Team at Riot where things stand with the Abyssal Scepter rework. I understand it is iceboxed for now even though it is currently on the PBE, but with the recent AP item changes, I feel now would be a good time to update players on what is happening with the item and if there is possibly another AP/MR item in the works that will "fill the hole" that Abyssal currently fills as the go-to item for AP mages against magic damage without sacrificing their own damage. I just thought I would ask about this as the PBE Abyssal looks promising on a lot of champions, but I'm unsure of when to expect it. Thank you.
