Subal D300s back?

There was talk about Subal releasing a back for their D300 housing that would work with the D300s. Is there any truth or news of this?

Thanks,

Retrofits are available for both ND30 and ND300 housings, and the price is $1528. The retrofit is a replacement housing back without viewfinder.

Is there any retrofit for the D200 housing?

Some of these will be available in about 10 days I'm told. I don't have a final price, but it will be more expensive.
