yes it is superior..no question..but is that enough to warrant a upgrade as the OP asks?
...ive spent quite some time pixel peeping the test images at image resources....and i really cant see the that K5 is that much better....the washed out DR at High ISO is equivalent on both bodies at respected ISo
eg the K5 is just as bad at ISO 3200 as the K7 is at ISO 1600....and anything above 6400 or 12800 on both bodies is pretty woeful
so I vote keep our K7.....
...I am

I think you are right in saying that K-7 iso 1600 is better than the K-5 iso 6400. I checked the "Imaging resource" shots and the K-7 at iso 1600 is significantly better.
But, no one really claimed K-5 iso 3200 to be as good as K-7 iso 400 (that is a 3 stops). Actually the advantage diminishes with lower iso's , so if the high iso advantage is less than two stops at lower iso's it would be even less,
K-5 does indeed have a huge amount fo detail in the shadows, but that alone may not be enough of an advantage for me to upgrade. I was really hoping that I could use iso 6400 as well as iso 1600 with the K-7 and that doesn't seem to be the case here
that's true I may have been carried away with ISO 400=ISO 3200...
but at the same time I've read many posts on this very forum saying how great the K5 was at ISO 25600..giving us K7 owners the belief that the K5 was indeed better by at least 3 stops at the High ISO end....eg the 25600 was as good as the K7 at ISO 1600 { the last ISO setting for me that's usable on a k7} .. that's clearly not so..
the K5 picks up where the K7 left off...and from a Pentax perspective a necessary upgrade to stay competitive with the competition, after all no ones going to buy a K7 with a D7000 clearly better than it....but and heres the BIG But...if you have already bought into the pentax brand with a K7 purchase..then for us..the upgrade path is less clear...unless you must have the latest and slightly better product,
Im going to wait until the K3 is truly three stops better than the K7..that will have me running to the store with cash in hand...
