I am not sure when they will be available, but I am sure you can place an order now. Production generally is still backed up a few months.
R-9s in the current finish will continue to be available -- except that they will have the new G-10 grips that can be upgraded to CF for a price.
I think its too early to say what the self-lubricating finish will mean. Just speaking for myself, and not the factory, I would see the lubricating properties to be a back-up to lubrication. I personally wouldn't run the gun in a dry condition regardless. Besides, the only thing it could possiblly lubricate is the slide to frame interface. I say keep lubing as usual!
