Techcrunch published a new chart released by Gartner in July 2008 about the Hype Cycle for Emerging Technologies.

Cloud computing is reported in the diagram, rapidly approaching the highest point of hype and expected to reach the mainstream adoption in 2-5 years.

Interestingly enough, virtualization technologies are not included. 
Hardware virtualization can be safely considered a mainstream technology at this point but OS virtualization is still confined in the hosting niche, application virtualization is in early adoption phase, and storage virtualization is so vague that the industry can’t agree on its definition yet.

The virtualization.info Virtualization Industry Predictions has been updated accordingly.
