Page 1 of Sopranos Season 4: R1 or R2?

Basically i want season 4, i have 1-3 from R1 but they released S3 R2 in the same packaging as the R1 editions, if they do this with S4 the only other thing is extras, does R2 get all the same stuff as R1 with 5.1?
I`ve tried a couple of comparison sites but none have it listed yet....
Anyone shed any light?

Go for the R1 so that it matches exactly to your first three seasons. The Season 3 R2 box may have looked similar to the R1 but it was not actually the same, the box opened out into some sort of fold out sleeve. The R1 of course features the digipak inside the box which you take out and then open up to reveal the four discs. I have Season 4 on DVD (got it yesterday) and I have gone with R1 every time.
