A double edged sword i guess
well if 7870 would be out of production , then yes , 7890 would made some sense, but since 7870 is SUCH a SELLER card ! no wonder partners refuse...
Personally i think they will sell it for 270$ targeting 660ti, when in theory , if overklocked to 1ghz it will be as fast as 670.
So, if 7890 will go for 270$ ,then AMD send 2 of them in Massachusetts, got my money ready.
