I note that certain language on Get Lion in July. Only from the Mac App Store.—including that page title—hints that Lion will be available, eventually, in a more traditional form...
Users who do not have broadband access at home, work or school can download Lion at Apple retail stores and later this August, Lion will be made available on a USB thumb drive through the Apple Store® (www.apple.com) for $69 (US).
