T3 Subsystem Industry Materials - Electronic and Engineering

With the combination of the Electronic and Engineering Subsystems, will the industry materials tied to them such as the datacores be needed after July 11th? Interested to see how this may impact those that have been stockpiling these materials and invested in the BPCs to T3 subsystems.

I would expect datacores and relics will be converted to core while subsystem BPC are converted to the closest equivalent - which may or may not please their owners.

Edit: Bill of material for subsystems is not changing at this time. https://meta.eveonline.com/t/strategic-cruisers/8414/28
