Looks like an interchangeable port system (probably the same ports as the A6xxx/A7x housings), vacuum valve port, access to all controls including the rear dial, EVF access, optional pistol grip, etc. Judging by the tags, it's compatible with models III through VI, but not the first two. The basic port isn't particularly exciting - it looks like it's built to allow RX100 VI to shoot at its wide end without vignetting, so it's too wide to take wet lenses, but if the port system works sufficiently well - i.e. the dome tubes are sufficiently short for the lenses to clear them, and there is a macro port to mount diopters/wet wide lenses, this may shape up to be possibly the best RX100 housing on the market.
