how long days to wait?
It has been already asked several times even OP can't tell or provide a date when the new project will be launched. So just wait for his next update. @fufufuwu will let us know if it's ready but I'm expecting it would be this year. Since he said they needed more time, it could be a couple of months.
... and it could be a couple of weeks .. or a couple of years
No that won't be the case. Unfortunately due to COVID-19 the work is slower than it would be, we need to take care of the close ones that are especially in need.
Most stuff on the frontend is already in place, backend still requires some work. We will keep you updated when the progress will go forward. Take care and stay safe!
