No... they are just going to rent the place, set up booths there, and when people want to buy they are going to shoo them off by telling them that they aren't selling at the expo
Apple themselves don't sell their products at the expo it's the companies such as ClubMac that do. I couldn't see Apple selling anything at MacWorld expo because for them it's to launch new products not to sell their own. It's also to expose the consumers to Apple vendors.
