Most likely it's an issue with field curvature. Notice that dpreview explicitly warns that the soft corners are evident for the shooting distance of their test shots. I'm sure the lens would fare better under real-world shooting distances.
I noticed something very interesting in the DPReview studio shot (RAW):
The per pixel sharpness in the center is worlds better than current APS-C cameras with Canon or Sony sensors. This is probably not only the lens, but they may have done some modifications to the filter layer on the sensor, effectively a much weaker AA filter.

Hmmm, interesting. It also seem to resolve a bit more detail in the center region than Nikon D7000 at ISO 6400.

That is indeed remarkable. This is exactly what I also noticed from shots deriving from the Powershot SX40HS a friend showed me. When I studied his images closely I had to conclude Canon did something extremely well in it's line of light processing through the combination of lens, micro lenses and filter layers and probably postprocessing the sensor data to correct residual abberations. It's very promising to see how well modern lenses and tight pixel constellations can perform. For that reason it's even more remarkable that some of Canon's latest models have been presented at lower resolutions than it's predecessor. However, for the moment this kind of technology is not for EOSfun (yet)
Remarkable indeed.
I'm glad to notice how well the sensor in the G1X perform either in micro contrast and noise department given the small pixels.
I'm not interested in the camera per se but in the rumored 5D mkIII 45 Mp based on the same sensor, so I don't bother the (poor) edge sharpness which is lens-related.

As the comparison cameras I chose 5D2, 7D, and G10. Of the four, the 5D2 looked softest in the corners and to my eyes the G1X didn't look much worse than any of them. I hope TDP.com does his typical lens comparison using the G1X.

It looks like there is no Anti-Aliasing filter.
There is pretty severe aliasing in the middle of this crop:
Ah, thats what I saw. I though it looked over sharpened to me as I commented in the other G1X thread. The shadow detail looks really good - especially compared to the G10.
