Functionality of Files Processed with Photoshop CC

Question

Adobe has stated that Photoshop CC users will have access to all files saved on their computers.
What will be the functionality of files processed with Photoshop CC and saved on my computer if I no longer subscribe to Photoshop CC?
Adobe will introduce new functions such as Camera Shake Reduction to Photoshop CC.  Let's say that I use a new function on a layer or as a Smart Object, and then save it on my computer, and then end my subscription to Photoshop CC.  Will I be able to open the file with my layers intact and editable in any program other than Photoshop CC?
If I save the files with the layers merged as TIFFs or JPEGs I assume that I will be able to open them with most photo programs. Let's say that I do not save merged files and I am willing to sacrifice the layers.  Will Photoshop CC be required to merge the layers and save as files that can be edited in other programs?  What happens with other file types such as PSDs?
Let's say I own CS6 or previous versions with perpetual licenses.  Will I be able to open and edit files in CS6 with layers created in Photoshop CC?

Eric, you need to clear the URL filed before pasting another into it:

[EDIT]
Having read the link, it is not quite the disaster Dave Cross makes it out to be.  While the new features would not be directly editable in CS6 or earlier, you could absolutely still use the image data in those layers, and make further edits using the features and tools in whatever copy of Photoshop you were using.  The Shape layer which used the new radius corners tool in CC, is still a shape layer, but even if it had been rasterised, you could select it and turn that selection into a path, and edit that path. 
I am not so sure about the ACR filter layer.  I'd like to think that the results of using that adjustment layer would be apparent in whatever that adjustment layer had been applied to in Photoshop CC.  So you'd still have the benefit of the edit.  Dave made that over complex by nesting the ACR layer in a smart object, and I could only guess at the consequences of that.  But the bottom line is you could still open a PSD file created in CC, and have all the layers, and most of the information.  You might even have the outcome of all or most of the edits made in CC.  If you are worried, put a copy merged layer at the top of the stack while CC is still working for you, or just keep subscribing to what will continue to be the world’s best raster image editing program.
