Maybe they'll release a "Whoops - We Called Last Year's Version the '75th Anniversary' Set But It Was the 74th Anniversary so Here's an Actual 75th Anniversary Box!" next year...
On the 2D Blu-ray, the digital glitch has NOT been fixed. I'm not sure about the line you mention - please point out its exact location in the film and I'll check.
I'd be shocked if it'd been corrected, though - I compared the two and found zero difference between the 2009 and 2013 2D Blu-rays...
