I'm wondering this as well. I'm in the market for a new Mackbook, and I believe I'm going with the 11 inch MBA. I'm looking to buy in the next few weeks, and the 12 inch would be nice, but not a requirement. Especially if there's too long a wait. My needs are definitely not hardcore at this point, so the 11 inch should be fine. If they do decide to refresh them on the 24th, it's highly likely that I'll purchase that rather than wait on the mythical 12 inch Retina. Unless news leaked of the 12 inch MBA being priced at $1,000 or below prior to the 24th (if that date holds up), then I'll be perfectly content with my purchase.
