I understand what you are saying however I have charted the bitcoin value/difficulty for the last year and it is at an all time low.
Basically, hardware or any kind should be worthless right now.
I think SlyFoxy12 is right...there is a bunch of noobs out there fueling these prices thinking that at ~625CAD mining bitcoins is gotta be worth it however when they realize how hard it is just to make a single bitcoin they will learn.
Oh well...what it is is what it is I guess
Not totally right though, if you look at someone like the units KnC are putting out are making bitcoins easily, the problem is you have to really gamble on which hardware maker will actually do what they promise unlike BFL because you have to preorder, you can't wait for a steady supply line and you have to assume that without major price increases you'll only have a small window to make ROI until prices rise, but to be fair, prices will keep increase while there a shortage of decent equipment out there.
