I'm pretty sure it's not gonna have an extra track. I know what you mean tho. Whether or not it has a different insert I have no idea.. I would dout it in this case, but...I haven't seen (or heard) any version(s) yet of Deliverance so I'm only speculating.
My only gripe with digipacks is they don't hold up well. Maybe I'm too rough, but I need the protection of a jewel case. I'm like a tiger when I gotta hear that music..NOW!
Even when I TRY to be especially gentle (like with In Absentia recently). It wasn't even 2 days and the spine of it had a little rip in the corner.. I'm like FUCK! FUCK!! FUCKA!!!!
I think digis LOOK cool, sometimes a little more interesting (like Katatonia's Last Fair Deal, and the latest Immortal the way they unfold) but like the Porcupine Tree digi is more like a promo, too thin, I don't like that one at all. Sometimes, like my old Arcturus "Aspera" digi has a hard cardboard side (with tray) and a little slit on the other cardboard side with a slit for the booklet (and it's the right size to fit in the cd slot)...that digi is pretty cool, even tho whenI open it, the booklet usually falls out that piss me off... and it's beat to hell with so many listens. So it's more a matter of being able to care for them I guess.
I'll enjoy having a digi of the new Opeth for my collection, but I'm gonna have take special precautions to protect it so it doesn't look like shit after a month of my greedy hands on it. ;-)
