The often-rumored slim MacBook Pro may already be in production, but only in smaller models. Rumors from part suppliers speaking to Digitimes had 13- and 15-inch models coming in an initial batch of 100,000 to 150,000 units a month, but no mention of a 17-inch system. No reason was given as to why it was excluded, nor was there an indication as to whether or not it would come later or was gone altogether.
