I would not spend 1.6b on an ammy with BoA ammys coming in 1.0.7.
The relative value of that ammy (even if you never craft a single BoA item) will decrease steadily over time as people craft strictly superior BoA ammys and are therefore removed from the potential "buyers" pool.
This will decrease the demand without affecting the supply and thus decrease the price of that ammy.
Just my 2 cents! :D
