The Ricoh Theta Z1 is this brand's latest miniature camera for 360-degree, spherical captures. It can achieve these in a single shot at a resolution of 6720x3360, and can also be used for all-around 4K/30fps video. Furthermore, it is the first of its series with an internal storage spec of 51GB, which may overcome the limitations of previous Theta models.

51 GB? Put in a microSD slot and you can have 20x that.
There's a 1 TB microSD with V30 speed class, and at least 256 GB with V90.
So there is literally nothing new but a bigger storage option.
Z1 + $50 = new Z1? Well that's just sad.
So much for the new version everyone hoped for.
