A great deal expected soon in this (5)
I believe the answer is:
sight
I believe this clue is a double definition.
'a great deal' is the first definition.
(I know that great deal can be written as sight)
'expected soon in this' is the second definition.
(if something is 'in sight' it's expected soon)
(Other definitions for sight that I've seen before include "The ability to see - spectacle" , "Visual perception" , "A great many" , "24" , "Looking" .)
