sort of off-topic but related...do any of you have the steelbook blu rays released late last year and/or the 'saga' blu ray box set? i'm just wondering about the differences in bonus features. from a review i read the 2011 and 2015 saga box sets have no difference and include a bonus disc but the steelbook ones are all individual and i don't know if they include everything or not, and if whatever they do include is also included in the saga box set.
