That's the google translation of one of the recent texts. May or may not be legit.
Posted this as a comment but since it's relevant I'll post it again:Maybe it's not entirely true, but it seems like someone with one another in Blizzard has information about the new Magic Find. If my "friend" can you believe (so far all he said about the class changes were true):
Changing subjects lost relevance. Magic Find your growing "gradually" to your maximum possible level of equipment for about 120 seconds, the last item on the dressing. So you can not change gear before the last blow, unless you want to kite 120 seconds.
Added levels of excellence. You get a temporary "level of excellence" at each murder elite group. This number is always available on your character and you do not lose it when changing games / acts, etc.
By killing each 500toy elite group you get a guaranteed legendary item (level and affixes depends on the act and Magic Find, as usual). At this point, your "level of excellence" is reset to zero.
This legendary item will snap at clothing that will put you a choice: use it or sell at auction. Can not he borrowed and sold. This is done to make a partial withdrawal of legendary items, or they will eventually clog the economy.
System of levels of perfection was chosen because of its simplicity and efficiency. It is similar to the system of "signs" of WoW, which always rewards for the farm, even if you have no luck with falling objects.
They have spent a lot of time and effort to make the legendaries steep. They had to strike a balance between too frequent and too infrequent downs. With this system, and the fact that they will snap at clothing, they want to create a balance in the economy.
There will also be changes that are selected as affixes on class objects.
So basically there will be a guaranteed legendary drop once you kill 500 elites and then the counter is reset. This legendary will be bind on equip to prevent market saturation. At least thatís what I could get from the google translation of the page.
