I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">any time now</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for soon that I've seen before include "Before you can say Jack Robinson" , "Shortly" , "Early; readily" , "in a minute" , "Early, in a short time" .)
