I checked out what you said Vimes and Google did do a complete roll-through of my site 12 hours ago. They also did that last month. I wondered why they did it then because nothing was updated in the caches. My theory is they are realizing their crawlers are missing a lot with incremental crawls. Iím probably wrong and go with answer C.
