By that logic, the 550 should not produce a higher contrast image than the 760, but it does. They have a lower model in the 550 that outperforms the model above by some margin, therefore it doesn't make sense.
The laser engine alone might be deemed by them to be the major step up but if the picture produced is inferior contrast wise then again, we are at the mercy of the marketing suits. Also, the laser in the 760 is essentially just a more stable light source that allows a moderately higher colour volume.
The dual laser, higher lumens and better lens are the USP and step up for the new model, and the current one could and should be boosted a little software wise to widen the gap between the 550 and itself and with all the new features on the new model, the 760 won't eat into that market anyway due to the cost difference.
They will sell fewer 870's than 760's, so why not boost the 760 a bit to allow it to reach its full potential? It still will not affect the market the new model will be in as it still won't close the performance gap enough to do so. People who can afford the new model will not want the 760 as it will still be a lower performing model than the new one. But by the same token, owners of the 760 will rejoice in Sony giving them a nice little boost to get the machine working as it can and should
JVC have apparently sold way more Z1's than they ever thought. Imagine the backlash if they had taken the line of 'well it is selling great so nothing needs fixing'.
They have stepped up and applied numerous performance tweaks and enhancements to that model. Good on them!!
Also, the 760 has sold well because it was the only 'affordable' native laser 4K model around at the time and also due to the unusually moderate cost in the UK (amazing in itself!).
Saying it is selling well because its performance is good enough, is not correct. There was simply no alternative if you wanted 4K motionflow and decent lumens.
Tell me about it!
The difference however being, that graphics cards can be (and are) readily modded/hacked by the enthusiast fraternity. People can subsequently alter the BIOS/UEFI and activate features after purchase if they are prepared to take the risk.
The same cannot be said for AV kit where you are entirely at the mercy of manufacturers for any improvements and updates.
Also Quadro cards have optimised pipelines for CAD etc, which is also why the new Volta architecture has not come to Gaming as it is heavily optimised at the hardware level for AI and data centres and suchlike.
Pascal is still where it is at for gaming.
