I'm sure it will have some type of remote, though not LANC.
From Barry & Jarred's article: more remote control capability (in addition to the familiar remote zoom jack, the HVX provides for remote focus and -- get this -- remote iris control!)
I seem to recall from Jan's presentation at NAB that there would be the ability to use a firewire cable between two HVX's to record with matching timecode and metadata. Whether this will actually be a sync'd genlock record remains to be seen, lets hope it is.
