That's the VCT-VPR1
, and there are also a new VCT-VPR10
(carbon fiber tripod) and VCT-VPR100
(twin shank tripod).
No, the first two aren't immediately compatible with the A99, but they can be made so, with some limitations. They use the new Multi Terminal Cable system, introduced for the most recent wave of cameras. The port on the remote itself is the most proprietary part of the system, but at least two cables are available with that connector, one adapting to a Micro USB Type B connector (Multi Terminal), and one adapting to the familiar corded remote commander connection (Remote Terminal) for shutter release. Unfortunately, it appears the two smaller tripods only come with the Multi Terminal cable, thus limiting their utility to the A58, NEX-3N, DSC-HX300, and some Handycam models (so far). The RM-VPR1
(smaller remote without a tripod) comes with both available cables, and the VCT-VPR100 (biggest tripod with remote) comes with four cables (Multi Terminal, Remote terminal, A/V R, and LANC) but if your camera has the old remote terminal, it will only be able to use the new remote for shutter release; ignoring all the rest of its special functions such as initiating video capture, toggling grid lines, or controlling zoom.
It is worth noting that the Micro USB Type B port might be present on more alpha models besides just the NEX-3N and A58, but it is just these two models so far that use this port for more than just mass storage or PC connection.
