I think we all wish for lower prices, but as demand for the D800 is outstripping supply, we may just have to keep on wishing. At least we have a replacement for the grossly overpriced D3x
Dx came about because it was difficult / expensive to produce a full frame sensor, that is no longer the case. Dx will be with us for a few more years, but the 24 x 36 format has stood the test of time and will be with us long after DX has joined the likes of half frame
( just my ten penny worth)
may be we should hibernate this thread for a few years
Bottom line is that the mid-ground (DX) is indeed being squeezed by mirrorless/P&S/EVIL/etc crap from the lower end getting better (still not 'good enough' IMO) and for now, relatively cheaper and better FX from above.
In a couple of years time, the lower end may have evolved to the point where $1500 is what can be charged for the entry level dSLR (not $600 - $800 or thereabouts).
This year, and in response to the latest D800 introduction, we should see the start of the next generation DX (D3200). It is moving up in MP count and overall performance, and I bet price too as marketing decide low end crap displaces CURRENT (i.e. D3100) dSLR models.
Hibernate this thread? Not for more than a few months...
Much as I'd love to continue contributing to this thread, I have a magazine deadline looming (end of the 12th) so will be busy doing real work for the next two day :-) which means no or very few comments from me until towards the end of this week.
