To be fair, nobody saw the cloud thing coming and MS had never mentioned it before.
There will probably be some kind of demonstration at E3.
I never said they did see it coming, I said it is the last in a line of things people have either conjured up or added more significance to in order to give some sort of better performance than their silicon allows ...... all due to the fact that the PS4 clearly has better hardware.
I'm sure we will get a demonstration, we have had demonstrations of lots of things at E3 over the years from all 3 platform holders that promised a new world but never saw the light of day or amounted to anything meaningful.
