The thing is, some people have left, okay. The second thing is, for those who didn't, was the theme not fine for them? skrab admitted it for instance.
And no, award will not be given unless those 3 entries meet the requirement. Sure it's not his fault (that's clear), but the award loses its meaning if it is given.
I propose to close the thread, give him a symbolic prize for his effort and you guys create a thread in the Contest Submission to discuss a more appealing theme. How would you feel about that? Unless you still want this extended. Though 2 entries is not acceptable either.
