Starting to think the people behind this don't care about long term success of this project.
The cap will be announced closer to sale, as stated. No one will be able to buy in the sale before the cap is set, and announced, days in advance. There will be no mystery on the cap, you will have ample time to see it (days in advance) before the sale goes live.
This is nice update good to know about this project has very good reputation I think so many people were interested to know more details about upcoming ICO. I hope this official response would be helpful for them.
You're right, this ICO is looking very promising.. We have to wait a bit again, in order to invest something in this project
In the meantime you can participate in various bounty campaigns
