* Google X - moonshot projects that aren't software centric.
* Google Fiber - mainly a infrstructure setup. May share some stuff in piper.
* Google Ventures - investment arm, not code related.
* Google Capital - more investment stuff.
* Calico - R&D for biotech.
Anything that would be software centric will probably still live under Google inc. As well, you are forgetting so many products that Google has. There are various lists of them out there [0][1].
