IMO the reason we haven't heard anything on the pump is because the talks with the first company failed and they have either moved on to another company, are working AGAIN on additional testing or prototypes, or the company is making internal personnel changes.
For the record. There is NO quiet period on the Cura. NONE per DK's last CEO update. Is the Cura in trouble or they have changed directions? Maybe some testimony from Donnelly would be appropriate at this time.
