From the GPN:

The Players Committee will release the first set of virtual cards to the playing community on March 4th, 2002. This set will look to compliment Decipher's original Premiere set. With new characters, weapons, device, effects, and interrupts, these first cards will be the pilot program for the Players' Committee release of subsequent sets. Each set will release every 3 to 4 months, Virtual Set #2 will release May 6th, 2002.

The Way It's Going To Work
After preview week, which will run February 25th to March 1st, the full sets will be available via decipher.com. They are going to be in .pdf format so you will need Adobe Acrobat Reader. Print out the new gametexts, cut them out, insert them in your opaque sleeves where the referenced card already is and BAM you have a brand new gameplay. With this new gameplay, you will be able to create new battles and pit Luke against his father one more time.
