It says trophies right there on the box art, so yes.
They've also done this on games like Metal Gear Solid 4 and Saints Row 2 on the greatest hits editions. The boxes actually had trophies written in the same spot, with no trophy support. I've held a physical copy in my hands. Granted those weren't "5 year anniversary editions", but it still brings up the question is this too good to be true, for those of us that care about trophies? It'd be nice to be able to get some sort of concrete answer from someone from Bethesda. I'd gladly play through my favorite game for my.....what 5th time to get that Plat.
