Hi Mark,
No need for you to apologise. But every need for Adobe to hang their collective heads in shame.
Quite apart from being mean spirited if they do go ahead with this it's the cynical attitude of making this policy change so late in the CS5 product cycle together with an attempt to sneak this announcement out by way of a poorly subscribed blog that galls me. For many years I've regularly updated PhotoShop on alternate releases simply because I couldn't justify the expense of upgrading every year. But perversely Adobe may have shot themselves in the foot over this as my workflow starts in Canon's DPP, where I use Canon's own knowledge of its lenses and sensor to produce the best possible RAW conversion. From DPP I batch export the desired images directly into Adobe Bridge as TIFF files from whence I do the initial post-processing in CameraRaw and then export to PhotoShop if any further tarting up is required.
Bottom line with that workflow is that I am not dependant on PhotoShop so far as RAW conversion is concerned which takes away one major reason to upgrade. The only other reason I might have to upgrade would be some new killer feature. There were some neat new tricks in CS5 but none that I could see myself using and I'll take my chances that the same will apply to CS6.
I actually believe that the suits at Adobe also realise that the well of new killer features has pretty much been exhausted for mainstream users. As a result they, like a number of other companies, would rather we moved on to a subscription basis, of which coerced annual upgrades are just another variant, so that they can keep the cash rolling in despite slowing the pace of innovation. I don't lease cars, preferring to own them, and cars wear out. But software doesn't wear out so I'm certainly not going to lease that. My x64 PhotoShop CS4 will keep on chugging along as good as new and the only reason it might ever stop is if Microsoft rips up the road and prevents "legacy" software running on some future release of Windows. But even then I could run PhotoShop in a virtual machine with a compatible version of Windows. By the time that needs to happen the hardware will be more than fast enough for such virtualisation to be invisible.
As for Adobe, forum policy forbids me to say what I really think...
Bob.
