The full specs are out for Ricoh Theta V and they are a huge disappointment: https://theta360.com/en/about/theta/v.html
Image resolution matters a lot to us, so here is a comparison between the S (former flagship) and V:
S: 5376 x 2688
Yes. Except for the difference in formatting (I actually copy pasted from two different spec sheets), they are exactly the same. A lot has improoved in the video side, image processing and the V runs Android so developers should be able to create applications. But for still images, there is no good reason to upgrade.
