Um, people have been selling +41 crystals on GTN for like a long time now. Seriously.
Its not the stat of the crystal that was exclusive to pre-order but the color yellow-black, and you get access to a vendor to buy them from. This has not changed its still exclusive at this time.
DDE was never sated as a limited and they never stopped making or selling.
CE was limited.
And the only exclusive digital items was a pet & the CE store. They now added a banner for CE but this can be traded/sold.
