I doubt they understood the question about ISOS because I really doubt they will be pushed thru WU. They will already be pushing a billion 2gig ESDS thru and they are going to add another billion 3.5 gig ISOS too? I doubt it.
So far with build 10162, they have kept up with all of the current updates moving toward RTM, so I would assume they will continue as the message states.
