I'd like the low ISO too, but it is interesting to see over at DXO that the A580 has better ISO 100 than the A900, so I'm both hoping and expecting that there will be improvements with the low ISO too; less noise and greater dynamic range.

And there's speculation that the really high ISO might be done the same way that it's done on the NEX - several shots fired rapidly at very high ISO and then aligned and merged with the purpose of getting rid of the noise.
You can't use it in every circumstance, but it can work exceedingly well and is not just a gimmick - using it, I can shoot at ISO 6400 and get shots that are at least as clean and sharp as a single shot taken at ISO 1600.

I'll be interested to see what the so-called 'NEX Pro' has. A 24MP sensor, a good EVF and build quality (to match that in the A77), and no translucent mirror. What's not to like?

Just break out the ND filters, if you're gonna have a "semi translucent" film on one end of the lens you may as well throw one on the front end too

Because there is this idea among ignorant marketing types that higher numbers sell(except in golf equipment sales).

Kidding aside, I'd guess that for a sensor to be usable at ISO 25 it would have to be less sensitive overall, or it would just saturate. So your ISO 200-3200 sensor would then be ISO 25-400, not counting "extended ISOs". Of course it's not so simple as that but I don't think I'm too far wide of the mark.
