 We know we need CMYK sooner or later, but higher bit

 IMO. Maybe in a stable version 6-8 years from now with

Hey, I may not live that long :). Krita has had CMYK for 
years. But of course Krita lacks the full feature set of Gimp.
Maybe some of that Krita code could be lifted for Gimp, just 
as InDesign lifted important features from TeX.

The debate on what ID lifted and what it didn't will never stop, eh?

There seems to be a recently growing trend to solve GIMP's bottlenecks
by introducing external plug-ins that do some fancy stuff and run in
16bpc mode, e.g.:
http://www.mm-log.com/blog/2010-07-09/adaptive-saturation-curve-labcurves

You might like getting Mike to code quick patch-ups, no?

Of course, mating the goat and the wilber would be preferable.

There is more to say.

Right now the top priority is to get GIMP 2.8 released. The current goal 
is late 2010. GIMP 2.8 does not have support for high bit depths.

Once GIMP 2.8 is out, we will start phasing out the legacy 
8-bit-per-channel code and replace it with GEGL. In other words, we will 
start for real to introduce support for high bit depths in GIMP. There 
is no schedule of this work, so a date cannot be given. It is reasonable 
though to expect this work to go on for say 2-4 years.

Regards,
Martin

And what is the priority/schedule for CMYK?

I think 2-4 years is more than enough for CMYK (hopefully).

Meanwhile, give separate+ a go. It gets the job done, and very
reliable. Latest version supports clipping paths, and saving to CMYK
TIFF, JPEG, and PSD. I'm not sure about reading those files back into
Gimp, but I think it was mentioned somewhere it can be done. I've
never needed to do it myself, though, so you're on your own.

I've given an overview of the color management in Gimp and part of it
covers basic separate+ usage:

Prokudine,

Veering a bit OT now, I've tried to use CMYKTool, and got an
impression it was a bit redundant for separate+ users. Does it have
anything to add (or do anything differently)?

Well, if you *have* used CMYKTool, you couldn't possibly fail to
notice the big thing called live soft proof or the small thing called
displaying per-channel ink density value for the point under mouse
pointer (right below the big thing) :-) Or how CMYKTool allows
creating CMYK files in a color-unmanaged way, which is also desirable
in some cases (implemented by a request, in fact).

I don't see how either of them make the other one redundant. Wise
people use both, depending on what they are trying to achieve.
