Following concerns expressed during the lead-up to this week's Apple media event that the company would be unable to launch the Retina iPad mini in any significant volume before the end of the year, supply chain analysts continue to expect very low supplies of the device when it launches next month. Shortly after Apple announced the new Retina iPad mini, IHS iSuppli analyst Rhoda Alexander noted that supplies will indeed be "severely constrained", according to CNET."The supply for that product is severely constrained," said Rhoda Alexander, director of Tablet and Monitor Research at IHS iSuppli. "We don't expect to see meaningful volume until first quarter [of 2014]."
