TIW died a slow painful death. They slowly began nerfing it a long time ago.
Years ago, when it was DDE, it was such a great value. Then they the changed the name (which I understand, it was too close to DDP and confused the heck out of the servers at times). Then slowly the price for TIW began to creep up, while at the same time WDWs choices began to push me out of the desire for Table Service (insane pricing, combined with lower food quality, and the need for planning reservations months out). I had a DDE/TIW card for about a decade (or more) and then I gave it up and never looked back. I think WDW is glad to have finally killed it.
However, if they brought it back, and brought it back to the point were it was a value to me, I would consider buying it again.
