Evidence is growing an iPhone 5S (AAPL +0.4%) will arrive around mid-year. Mizuho says checks indicate an iPhone refresh in June or July, and that March quarter iPhone shipments will fall to the 35M-40M range (in-line with consensus). Wedge Partners: "We understand Foxconn is currently prepping production lines for ... iPhone 5S production, which we believe is scheduled to begin in the April timeframe." The firm thinks the 5S will be unveiled at the WWDC conference (typically in June), with sales likely starting in July. MacOtakara recently reported Foxconn has begun 5S production.
