It's been announced during Blizzcon that a forthcoming patch will have a new set of more powerful items and weapons called "Ancient" items.
These are typically around around 20% - 30% more powerful with armour item stats ranging from 500 - 650 rather than 400 - 500 as can be seen below.
I'd like to see crafted legendaries with these stats since I tend to make use of a lot of crafted legendaries (would be odd to see a newly crafted legendary become ancient just after being forged though )
Probably best to save up your Ramas gift unless you have some spare (just found 1 myself yesterday)
Along with the more powerful items, I'd like to see the torment difficulties increased up to 8 or 10.
