I believe we are in for an exciting couple of weeks. The Chicago show is coinciding with the expectation of progress on the certs front. But IMO I don't believe we even need to wait for the actual issuance of the official certs- which can take 4-6 weeks after the testing is completed. I believe that once the testing is successfully completed- hopefully very soon- pending sales can be finalized. Then we are literally in business. And then I expect that there will be a very impressive PR announcing this.
