Perhaps this is more aggressively priced than what is speculated. I don’t see people waiting in long lines like the early iPhone launches, but if this is accompanied by a large advertising campaign I could see it driving traffic to stores. It’s likely to be the “star of the show” on Wednesday. I expect Apple will do the press release updates to the MacBook Pro, iPad Air, etc. first and unveil the MacBook on Wednesday either at the events or earlier that morning through a press release with a video on Wednesday.
