Current featured crystal in Black Iso Store

When the Black Iso Store launched last year there was the opportunity to buy one featured crystal for the newly-released champ (I think it was the Doctor Doom featured crystal, so in November?)
Has Kabam said anything about introducing this on a permanent basis or was it just a tester/one-off for Doom?
It would be a really nice incentive to have this in the Black Iso Store each time it refreshes (as well as a discounted featured 6* crystal someday...)
