no download link doesnt mean it is dead.
and "delayed" means, it's not ready yet.

if you are not really sure, (asking author etc.) don't speak so ceratin. there is words for stating that you are not really sure like

"im not sure but...","i guess ...","maybe ..."
but to say
"Sadly, it's dead." -> you have to be sure.(it's a strange ability to deduce that a project is dead because there is no download link.)
