Quantum, huh? I guess they decided to move to the atomic level where all the metals look the same [g].

Maybe we will continue with cards named after the atomic particles...

ELECTRON
PROTON
NEUTRON

Hilton Las Vegas could well have a top level card named the QUARK, since they have his bar there. Data in Startrek has a positronic brain, so a POSITRON card is sure to follow.
