This isn't really the reason, though. The sensor in the $7500 FF D3x only cost about $450 more than the one used in the $1100 aps-c D7000. Right now, we may be looking at FF sensors at around $300 cost to the body manufacturer, if I remember Falk's numbers correctly.
Yes, Pentax (or anyone) could make and sell a bare-bones FF DSLR for less than $1500 and make a small profit on it, but at that price it would eat into their top-end aps-c space, they would have to lower the prices of their aps-c bodies, losing margin there, etc...
So in other words it's not in Canon or Nikon's best interest to do that, especially when the higher-margin, $3000 D800 for example is on backorder until probably late-summer.
A disruptive player like a Pentax who has less to lose could maybe do it, if they wanted to really shake things up, but they would have to sacrifice aps-c sales as well.
A body priced around $2200-2500 probably makes more sense for Pentax right now.
