This is kind of a clickbait title, seeing as it's just another name for DARK SOULS III Deluxe Edition, which is already available on the PC. : P
Sure, this new bundle might be $50, but they'll likely just reduce the price of the Deluxe Edition to match. The Deluxe Edition has already gone on sale a couple times for $55 on Steam, so it stands to reason that it will see a price drop soon.
They had a nice system of making you play higher difficulties to access +1 and +2 versions of rings. (in case you didn't know, difficulty level has no bearing on getting matched in multiplayer, only character level)
But hey, let's through that out the window in the ringed city DLC. Did you buy the DLC? Have some +3 rings on the normal difficulty level.
