I own the CD-ROM version of the game, and after few years I wanted to pull it out of the box and install.
Sorry for the rant, but I've never received from Days of wonder a communication announcing that my purchased game would become discontinued.
The game is not discontinued at all. The "online" version you refers to, also have the offline game the previous version had.
