I remember someone posting about that thought a while ago - back when those glasses weren't released yet. Can't quite remember the explanation of the posters thesis anymore but at that point it sounded all very reasonable. Well, I ain't much of a techy so it might actually have been a load of bollox but since this glasses are available now I wondered if there is any truth to that rumour?
And please dont rip me apart if being wired or not doesn't have anything to do with ghosting :)

Certainly possible that the latency introduced by the various ICs that translate and transmit the USB signal to the IR emitter is enough to cause noticeable ghosting. When we're dealing with milliseconds and only 16-17ms between frames for each eye, even a few ms latency could be enough to cause a noticeable difference in ghosting. Personally I think the bigger issue is the shutter glass technology rather than the signaling/timing side of things. To give a similar example where milliseconds matter, there's people who swear wireless gaming mice introduce noticeable input lag compared to their wired counterparts.
That being said, I don't have a huge problem with ghosting/cross-talk and certainly not enough for me to give up the convenience and freedom of movement from the wireless glasses.

ms are significant in this cae, but any delay inside the glasses should by in single digit uS, which should be insignificant.
If there is no microcontroller in the glasses and it's all hardwired (and I've never looked) it should be nS were talking about.
All they have to do is receive the signal and reset the internal clock.

unless you think the time it takes photons to travel 3 ft is significant?
