Wizards of the Coast returns to NYCC!
Wizards will be having a booth there from the 6th to 8th February with previews, demos and convention games. They are also giving away D&D backpacks to anyone who subscribes to D&D Insider at the booth.
This is probably the only chance that non-subscribers will get to preview the new classes from PHB II.
Check out their schedule that is also listed at the bottom of the link.
