If I understand correctly, that gives you 4*36=144 mp in one shot? If they produce high quality raw files and not some jpeg or compressed crap, imho this system a clear winner ... and as a Canon exec, I'd really wonder how to counter this w/o IBIS.
I'm not sure about that. It might give a 144 MP file, but if so that's a lot of empty resolution. If the sensor is translated in one-pixel increments, then each pixel is sampling the same spatial area four times – but it's still the same spatial area. Each spatial area would be sampled through all three color masks, meaning no interpolation and thus increased color resolution. Actually only three images are needed for that, but two exposures through green may fit existing algorithms better.
The Zeiss system used full pixel moves to eliminate color interpolation (the sensor actually moved while the Bayer mask remained fixed). They also used
sub-pixel moves to increase real spatial resolution – but that only works if the sensor doesn't have microlenses.
Thanks for elaborating, that's very interesting! It's easy to forget (for me
that a (modern) dslr sensor doesn't simply use "pixels" and shifting isn't that easy.
I'm really keen to see how the real world resolution and iq of this sensor shifting with a common dslr sensor will be - if it works somewhat, I guess we'll see it applied in a lot of dslrs with IBIS from Sony & Pentax and the lot.
What appeals to me is that it seems to be a "freebie" done mostly by software, and even arguably shooting the same static subject without shifting is rumored to have some potential to raise spatial resolution for some patterns. If I could have done my ol' mushroom macro shots with this instead of plain 18mp, oh my...

Very stable setup, completely static subjects? I doubt Canon is particularly worried.
I imagine for architecture (inodoors and outdoors) and some landscape, this is a common scenario?
Sure, Canon demonstrated that they aren't worried about high-mp competition with the d800 or they could have designed an upscaled crop 5ds-type anytime in the past, but surely still there is some market share there. But on the other hand there are medium format sensors, too, for this, so probably Pentax will end up in the amateur, and not the "pro" market.
