Cons
Con Not yet released
It appears that the item is still a pre-order and that shipments will not go out until October 2016. This is worrisome as other cameras in the past have failed to deliver, which means it may be best to wait until an official release.
Con Poor image quality for the asking price
While there's no official word on sensors and image processors, expert reviews suggest that it's within the 5-6.5MP range. Theta produces reasonable images, but better images should be expected, given its price range.
Con Lack of expandable memory
Theta comes with 4 GB built-in memory which can only take videos of 4-5 minutes. Sadly there is no way to expand this memory as there is no external card slot.
