Another factor here is that with the announcement confusion driven by Sandy, a lot of people went into a holding pattern trying to figure out if the Nexus version of this would materialize.
And the Verge says that the Sprint variant comes with up to 32 GB storage and an sdcard so I am confused myself.
Either way, cloud or not, 32 GB storage is sufficient for probably most folks.
