'console son ultimately missing' is the definition.
I know nothing about this answer so I can't judge whether this works.

'having exes around' is the wordplay.
'having' becomes 'bo' (I am not sure about this - if you are sure you should believe this answer much more).
'exes' becomes 'xx' (two X's).
'around' means one lot of letters goes inside another.
'bo' put within 'xx' is 'XBOX'.
