Will ACR 6.7 really be the last ACR version for PS CS5?

In the lightroom journal article for ACR 6.7, http://blogs.adobe.com/lightroomjourn... there is a statement, quote:

"Please note that this will be the last update of Camera Raw for Photoshop CS5"

At present, there are two known major problems concerning ACR 6.7:
1. It does not support the new defringing of LR 4.1 RC2
2. It has a major rendering bug just as LR 4.1 RC2: http://feedback.photoshop.com/photosh...

Those two problems make ACR 6.7 "formal" incompatible with LR 4.1 final (because of the defringing) and you will get not exactly the same rendering (in fact, a faulty rendering) because of the second problem.

With that in mind, my question is: Will ACR 6.7 really be the last ACR version for PS CS5? Do we have to upgrade to PS CS6 to get a correct and fully PV2012-compatible ACR-rendering in Photoshop?

Have you tried the final release of ACR 6.7 and you're still having issue?

Yes. 6.7 is the final release full release. There is the possibility of a double-dot 6.7.1 for bug fixes.

LR 4.1 should get in sync with Camera Raw 7.1.

I believe that is correct. Looking at the bug number for the link that the OP posted, it looks like the fix was on the LR side in 4.1. I've asked the team for clarification.

If there is not going to be an update to ACR 6.7 so that it's fully compatible with the new defringing in LR4.1 RC2, could we at least go back to having Lightroom give us the option of treating it as a non-compatible file?

At the moment if you edit a RAW file in PSCS5 from LR4, you don't get the defringing carried across. The only way to get around that is to export a tiff from Lightroom back into the Lightroom Catalog and then open that in PS, which is a bit painful. If LR and ACR 6.7 are going to be incompatible isn't it better to treat them like they are? - so have the option either to render in LR and then export, or to ignore the incompatibility and render in ACR 6, as it was doing before ACR6.7 was released.

And given the way that the rendering bug really mucks up anything that involves both distortion correction and clarity/shadows, that should really be fixed in 6.7 as well as LR4.1 final.

Re: "could we at least go back to having Lightroom give us the option of treating it as a non-compatible file":

There is a workaround, at least for windows: Make a copy (!) of the photoshop.exe and configure it as an external editor. LR will recognize it as an "ordinary" editor only and will not attempt to render the image using photoshop's ACR. Don't forget to renew the copy when updates to photoshop are installed.
