Pixel shift is a really game changing technology that only Pentax uses currently since it has IBIS. Olympus did something similar to increase resolution. Only IBIS systems can do this while Canikon can't, and have to rely solely on the sensor's potential capabilities, which has limits.
The K-1
without Sensor shift at low iso's beats or is close to the other Sonikon bodies (810/Rii's ) in DR, which is great for landscape and product photography.
With sensor shift, it completely blows them away.
DxO knows about this and chooses to ignore this when its not that difficult to implement. Its like Dpreview harps over and over about incremental differences in DR but when a big game changing tech shows up, it just makes passing mention.
If you a a landscaper or shooting non-moving (generally) subjects and want to capture the highest DR, nothing else will do but K-1+pixel shift.
I doubt sensors without sensor shift will catch up in DR with pixel shift of 2016 in 5 or 10 years with on chip AD processing, back lit sensors and smaller/larger pixels or some kind of stacked/split pixel technology. I'd rather spend $1,800 for a landscape camera today than $10G to get the same DR in MF.

To be fair to DxO, I'm glad they issued this timely Update to DxO11. Its Much, much better, IMO strictly, than anything else for manipulating K-1 png/pef files and takes care of lens softness, CA, aberrations (noise, what noise on K-1 at low iso's)
very nicely. Since I shoot at low isos, I turn off NR in DxO11 to preserve maximum detail.
