Wizards of the Coast will be co-sponsoring the mass GenCon gaming event, which they do every year. Wizards will be showing off Dungeons and Dragons 4.0 and a new “Living Forgotten Realms” campaign setting.

This is good for GenCon, who needs a successful con to pay off its debts, and good for WotC, who needs a successful con to receive the money they are owed from GenCon.
