With the release of the 28-70 and its massive weight that indicates to me they are trying to move the Pro's and Advanced Amateur to mirrorless with a new level of IQ and performance.
Right, I suppose you are correct here. Rereading, the press release seems much more performance oriented. Compactness is secondary, and frankly appears to be a pretty thin argument considering how huge a couple of the new lenses are. The comparison isn't EF-M to RF, it's EF to RF.
