Your question is easy to answer: NO!
But the answer is not as easy as you may think.
You can have several reasons to go "Full Frame",

like the better resolution

Not really, the nex7 has the same resolution as A99

But the A99 is not a class leader

, better low light

Half a stop, from NEX to A99.

Because of the SLT mirror, it is almost two stops to the D800/5DMkIII

less problems with lens defects

Why? There's no evidence that SEL has more defects than SAL?

, better DR etc

Less than 1 EV (again according to DXO)

For A99, other sensors can have more

. All these are technical immage quality things. Then there is the DOF control: The larger the sensor, the more control you can have over DOF with the same Field of view.

This one yes, DOF is the absolutely one thing where it is compelling to go FF.

So back to my question, is DOF enough to sustain a sensor format?

I think that you are narrowing it down to DOF, but overlooking a lot of other elements.

Low light: Nex-7 = 1000, A99 = 1500, 5DIII = 2300, D800 = 2800.

All FFs also have about 1EV more DR, and 1 bit more color depth.

I guess my view is more related to a NEX vs A99 discussion rather than NEX vs FF in general. I want to stay with one lens system and FF is not very compelling in that case. I can see how the argument is different with NEX7 vs D800 I suppose.

Curiously, the RX1 FF sensor measures out close between the 5d3 and D800. The A99 is an anomoly.
