No mention of Clustrix? The Spanner paper was in 2012. Clustrix started working on a "NewSQL" database in 2006 and had a product out in 2010.

One big difference is that Clustrix (YC'06) was a single datacenter consistent cluster, while Spanner can do multi-region consistency. It will be interesting to see what MariaDB does with Clustrix, now that they have acquired them, fingers crossed that they open source the technology.
