yes, Adobe will probably pull another Canon 5DII trick with CS5. Of course, the irony is that one of the supposed main benefits of having ACR as a separate plug-in was that one could easily just update ACR whenever new cameras were introduced rather than having to update Photoshop. I guess that did not work out from a money-making marketing standpoint for Adobe.
Well, you can do exactly that(update easily whenever new cameras are introduced), within minor versions. It's much nicer than waiting for the (always later) LR updates.
Adobe never promised that major versions of ACR would be compatible across PS versions.
Adobe has made it much easier to get new cameras to work in older software than any other RAW converter vendor thanks to the free DNG Converter.

Nope,
ACR2.x works with CS
ACR3.x works with CS2
ACR4.x works with CS3
ACR5.x works with CS4
Major versions of ACR are tied to the matching PS version. Minor revisions are shipped every few months during the lifecycle of the PS version. Major changes can happen in minor revisions such as the engine revisions in ACR5.2.
Note I'm using major revision/minor revision in the software sense, where the first number in the version number is the major revision, the second number is the minor revision and any additional numbers indicate pure bugfixes or build numbers. Adobe only publicly uses major.minor for ACR.

Of course, there are actually different versions of even DNG's, a fact that introduces confusion between those using older or newer versions of Photoshop. Things are never as simple as one would think. I ran into this issue recently with a student trying to use their older CS2 version of Photoshop with a Panasonic G1 raw file. She converted it to DNG at my suggestion as CS2 is dng compatible. Well, turns out it is compatible with a specific version of dng and some research turned up that she had to choose that earlier dng compatible version when converting in order for CS2 to read it. Earlier versions of PS will not read the most current DNG version. Common user problem apparently. So, all DNG's are not the same.
Adobe made no promises but did stress/insinuate when ACR initially came out that one major benefit would be the ability to only update ACR when new cameras are released instead of having to continuously update Photoshop. In the end, it's all about the money of course.

Why do you say "Nope"? ACR5 will not work with versions of PS earlier than CS4. Is that not what he said?

True and unfortunate. That's something Adobe changed recently and it's caused no end of troubles. As late as ACR 5.3/DNG Converter 5.3 this wasn't an issue, you just ran the converter and it worked on ACR2.4 and later.Adobe screwed it up and really needs to go back and fix it.

ACR5 only works with CS4 (and the compatible versions of Elements). Later versions will not work with CS4 (it's the "and greater" that I was specifically objecting to).
Well, it sounds like it's _been_ a dirty trick for a long time, then. I wasn't keeping up on this because I've been upgrading PS all along, but if the output of ACR is a standard like tiff or psd, I can't see why that shouldn't work with an earlier version. Sounds fishy. Don't mean to derail this any further though.

I'm pretty sure it's the hooks into PS and Bridge that are the issue. ACR is quite seriously integrated into the two applications and that is what's driving this. ACR doesn't appear to use the standard plugin API.
I'll just bore you with a hopefully final update about the backfocus issues I've had.
I've had two A850s: A1 and A2. I've had two 50mm lenses: L1 and L2. On A2, the L1 and L2 both need -16 micro adj. On the A1, L1 needed more than -20. Hence, L2 on A1 would probably need the same, but I haven't tried.
I picked up an A900, and L2 is dead on without any micro adj.
My concusion: Both my A850s were off. Why, I don't know. I'll stick with the A900.
