I think we have entered a time period where the weekly dividend will not be a huge catalyst anymore.  If it low, then it just AM re-investing for expansion.  If it high, it will be excused as a one-off from hardware sales of soon to be obsolete (and reduced in price) products.

What investors are looking for now is the % of the total network hashrate and things that effect that.  Specs on their new hardware, when it will be rolled out and start mining will be the movers.  If the competitors ship their new products before AM can start hashing away with there hardware, AM can easily be cut in half again.  If the opposite occurs, their will be upside - the amount depending on the specs of the H/W and the rate of rise in AM's share of the total network pie.
