I'd consider it, as I'll never buy into the SLT concept (don't really like looking through a viewfinder to find a telly at the end of it), but, as some have stated, would need some assurance from Sony that this will not be the last OVF DSLR - Sony's too capricious to deserve my trust on this and other matters (an electronics corporation, really, which also reflects on how slow it is in plugging gaps in its lens lines).
I find the A900/850 great, and so would like an upgraded A900. Live View; retaining IBIS (which for me is very important); increases in DR, megapixels and high ISO would be great; keeping the form factor and the simple, no-nonsense controls and interface - don't care about DSLR video.
Two things make it hard for me to switch to Nikon D800: lack of IBIS and a lens mount that is much less adept for the use of alternative mount lenses - for instance, wouldn't be able to use the Mirex+Mamiya 645 combination.
On the other hand, the D800 has LV, which is of great assistance when composing and focusing adapted MF lenses, particularly when using tilts, as any OVF will darken and mask when tilting farther than a few degrees.
So, yes, A950 please, with LV, IBIS, better DR, 36MP, better high ISO and retaining the Minolta 'ethos' in form factor and control - but don't spoil it by hinting that this will the last OVF Sony...
