Wow, just seen this this announcement from Musikmesse 2013, about the update to the Zoom H4N (which I have been using for years). The interchangeable microphone format is fantastic news!! I personally am very excited about the M/S option, just wonder what the capsule is like!! This is going to make working with a DSLR for filming very interesting indeed. I wonder what the price is going to be!The current information is
