I'd say it's very unlikely. There might be more examples but I can only think of one time that Shout had an individual release from one of their box sets.
Off the top of my head, I'd say this is the best price that Shout has ever offered. The Universal Horror Collections are $70 MSRP for 4 movies and the A&C set is $170 MSRP for 28 movies. Basically, these are 1/3 of the cost of the horror titles.
I can't speak to this movie but Shout has released a few of the Universal 1950's sci-fi movies in their correct AR on Blu-ray that were only MAR on DVD. Based on that, I feel safe in assuming in that they will do them right here too.
