I kind of agree with TFA here -- hear me out here. We went through a pretty fundamental shift in the datacenter over the last 10 years or so, and it's finally settling down. Of course there will be constant evolutionary progressions, updates, patches, etc we're basically done totally reinventing the datacenter. 10GbE, virtualization, the rise of SANs and converged data/storage, along with public/private/hybrid clouds - these huge transformative shifts have mostly happened already and we're settling into this new architecture. That's not to say there won't be patches and upgrades, but fundamentally, from a architectural design perspective, things have basically settled down in the datacenter. The major pieces and components of the datacenter are pretty much set at this point and now we'll just continue to innovate on top of this infrastructure.
