Wouldn't surprise me a bit. The double dip has really become a big part of studio strategy, Jaws is getting a new release (a 30th anniversary after the 25th anniversary release in 2000), and Universal distributes both films.
If Universal decides to create an anniversary release of The Blues Brothers, it would be nice to have both cuts of the film in one package, a commentary track with Landis and Aykroyd, and include the documentary from the original release- it's a really good one.
