BlizzCon 2018 classic worker scins and new BlizzCon 2019 scins from BW

Guys, 1 year passed, but we still didn’t receive classic drones, SCV’s and probes scins in market, why ? Blizzard promised, that The in-game items for Overwatch, StarCraft II, and StarCraft: Remastered will also be available separately in 2019—further details will be announced at a later date. And nothing happened since then, any thoughts ?
Even Ultralisk, Battle Cruiser and Carrier scins from BW appeared in ingame market for purchasing Blizzcon Virtual Ticket 2019, and still the same inscription: acquired by purchasing ticket for BlizzCon 2019, or through purchase when available.
