When the new model numbers come out, Apple typically has something up its sleeve.
The company has apparently registered new model numbers with the Eurasian Economic Commission. The assumption is that these numbers coincide with new Macs and new iPads being announced at WWDC next week. Russia requires companies to register all new products that utilize encryption tools.
The new model numbers (A1289, A1347, A1418, A1419, and A1481) are thought to belong to a 13- and 15-inch MacBook Pro, a 12-inch MacBook, and perhaps a refreshed MacBook Air. These have been pointed out to be new model numbers as opposed to current model numbers.
