The real problem with Diablo 3 was the RMAH. It's pretty damn obvious that the game's entire itemization and loot engine were tuned to make the RMAH more attractive and viable than it should have been. D3, along with every APRG, falls apart with terrible itemization.
The console versions are a surprisingly good port from what I hear, but an offline mode and no AH doesn't fix the underlying loot engine. "Loot 2.0" is coming to the game "soon". However, no one knows when, no one knows if it will actually fix anything, and no one knows if the console versions will get it.
If the PS4 version comes with the "Loot 2.0" patch AND it actually does fix the itemization, then I may play the game again. I have the game already for the PC, but I'd be willing to get another copy to be able to play on the couch in living room.
