From the pictures, there doesn't seem to be any weather sealing. I've asked, but it looks like it's under embargo for now - i.e. no information.

Erm... What use would partial weather sealing be? That is the same as no weather sealing. It is like building a tank with armour only on the front. It is only as good as its weakest part. So it might as well have no seals at all and be cheaper.
AKAIK there is no weather sealing on the DA17-70F4

I wasn't making any judgement as to the effect of partial weather sealing odd as it seems. I mentioned it because I recalled some comment elsewhere about "partial weather sealing" elsewhere.

1. When this lens might be released?
2. The likely cost?
3. Am I right in thinking that it only has partial weather sealing?
Thanks,
Jonathan
