Last year they had a couple of different items (t-shirt, sweatshirt, pin, Mickey ears, and glow stick), but they all had the same design. I would bet that there will be a pin again this year (along with the t-shirt), but I don't know about any of the other merchandise. With the 60th anniversary kicking off that same day (and the merchandise debuting), it's hard to say how fast the 24-hour merchandise will last. Last year, I think they had most of it (I don't remember about the pin or the Mickey ears) for most of the day. My guess says that any pin will sell out fast, but clothing may last longer.
