Question for Gemstone, about Barks's preliminary apple worm cover

[Daniel van Eijmeren]

According to 'Uncle Scrooge' 312, an inked cover preliminary of the 
apple worm cover (WDC 158) was scheduled for inclusion in 'Walt 
Disney's Comics and Stories 628'. Unfortunately, this didn't happen. 
And, as far as I know, the art is still unpublished.

Is there any chance that it will appear in one of the next 
Gemstones?

BTW. Reportedly, an interesting difference is that the preliminary 
version doesn't contain the nephews, nor the Halloween pumpkin.
