I love Nikon Rumors.. Whether the rumours of the D4 and D800 are true or not, it still makes for interesting reading.
A single Thunderbolt port supports a daisy chain of up to seven Thunderbolt devices; up to two of these devices may be high-resolution displays. Intended to replace many or all of the high-speed buses in modern PCs, just as USB replaced many lower-speed ports, Thunderbolt is meant to have the bandwidth and low latency to support high-performance systems such as eSATA and FireWire, as well as DisplayPort v1.1a through an implementation on its driver chip.
Nikon D800 – Rumoured to have the following:
… claims that the D800 will have a sensor carriage that can be removed by an authorized dealer. The rest of the specs: 16.4MP FX and 12MP B&W sensors, 3.3? LCD screen with a built in collapsible hood, new MB-D10i battery grip, 1/16000sec, full HD video at 120fps.
