Retailer's 3D Demo Days, new Pirates movie trailer highlight ESPN 3D's first NBA game

We're just a few hours away from the first NBA game on ESPN 3D when the Heat face the Knicks at 7 p.m. at Madison Square Garden, and now ESPN has announced it will have the "television premiere" of the 3D trailer for Pirates of the Caribbean: On Stranger Tides during the broadcast. While we wonder if that will become a trend for the network to show off 3D trailers for the slew of movies coming to theaters in the future, those who haven't bought a 3D capable TV but do want to see how the broadcast looks may want to check out one of the retailers (Best Buy, among others) participating in the CEA's Demo Days, coming back this weekend just in time for the game. Of course, that may mean choosing between Lebron vs. Amare and The Engadget Show tonight, but we're sure you'll make the right decision.
