A friend of mine has skated with both the standard and the Rev P99. Two negs she's noted with the Rev P99 probably also apply to the Rev CA, since they concern the carbon-fiber mounts (from the photos shown on the Wilson website, the mounts are similar, though not identical). The heel mount makes it difficult to do catch maneuvers in which you need to grab the back of the blade. The mounts also trap water and slush; they're a pain to dry thoroughly (I've watched her do it many times, and listened to her grumble).
Wilson is tight-lipped about many technical details. I once emailed them about the types and grades of steel used in various models of their blades. It took several attempts and a long time; eventually, the only answer I got was along the lines of "all our blades are made of the highest quality carbon steel". I have nothing definitive, but I don't think the Rev would have a higher grade of steel than the standard; therefore, edge life should be the same.
