I know it is not supported now. But is it possible to get supported by firmware update, or it must be a hardware update to allow target display mode? If the later is the case, iMac 5k sounds a deal breaker to me.
Got a tip for us?

Not possible as current thunderbolt controllers can't handle the bandwidth and that's one reason there's no external retina 5K display.
A future retina iMac will be able to do this but it's going to be with thunderbolt 3 and or display port 1.3.
None of those technologies will come by firmware update.

Technically can't they give us an update to support using it as a display in 2k or 4k mode? Thunderbolt can handle that.

I suppose.
Only they know exactly what they did with that custom timing chip.
I wouldn't buy it if counting on some future update to enable more functionality.
That's not really an Apple thing to do usually.

Yep, I mean perhaps some day Apple will give us a firmware update to allow us to use the 5k imac in target display mode *up to* 2k.
This might be impossible, I don't know how the internals look, but a guy can dream.
