I think it's unfair to say that the cell processor ever really undelivered. It never really had the chance to reveal it's full potential after Sony put too much weight on it to make for the system's lack of RAM. Despite all of this, we still saw the generation's best looking games in Uncharted 3 and The Last of US.
The problem, I think, with the cloud is that noone really knows about it. It's all just Microsoft per se, and people just kind of go with it. Sony at least demonstrated the potential of the cell processor to build up hype.
