LucasArts is currently showing off Monkey Island 2, LeChuck's Revenge, Special Edition at their E3 booth, and 1UP has posted a video of their visit. Or maybe at a bigger size for you people who need to fill up more space on your monitors. It covers basically the same ground as the IGN live video demo streamed earlier today, which we'll also provide for you just as soon as it gets archived online.
This video contains further evidence that the Concept Art gallery is going to be really neat. I'd say more, but I daren't spoil the surprise.
