“Within a decade Wal-Mart (WMT) shares cease to be listed on the NYSE as a result bankruptcy, being taken over/private, or being delisted by the exchange.”

The Wal-Mart model has run its course. Consumer preferences will run very far away from the specious "value" proposition Wal-Mart offers and a major customer backlash is coming. I believe Wal-Mart sells to people who would really prefer to go elsewhere but don't because of some constraint (limited income, geographic limits, lifestyle choice) that isn't going to hold up.
