I think it is not possible in the next couples of days, they need more time. If within a few days, they will have today's announcement so JACS holders need to wait a few weeks.
Agree with it, a development of good product for market, will need extra time. So yes, couple weeks or may even months will be required. Everyone needs to calm the mind for the good of this project. Besides, I realize now, if the dev force to list JACS at the current condition, the JACS token will instantly have no price in no time.
What you said is right, we should always for the company listing and developments activity otherwise, they will lose the coin value even though they lost in the exchanges. They need to release the update and developments otherwise they will lose reputation in the market. Of course, developments will take time, but they need to update the community in a timely manner.
