I'm sorry, while some time ago, the 20-F did state "The Company projects that such prototypes will be ready for display and testing by the end of 2014", I believe this timeline has been shifted to Q1 of next year as per the last NR. "This effort will enable and progress two of our current key initiatives which the Company is currently working on, a 100-nm ring oscillator which is a common demonstration vehicle for performance and an integrated 50GHz VCSEL device, both targeted for Q1 of 2015."
