The first preliminary review with full specs is here http://www.imaging-resource.com/PROD...tax-k3-iiA.HTM
As Kym has said, probably not a lot to encourage upgrade from K-3.
I would prefer a built-in flash for my use.
There probably isn't a lot to persuade me to choose the K-3ii over the K-3...I'll have to think a bit more about it and also see the local price.

Cheers,
Terry
