Must I forever have a CC subscription to open a CC PrPro project in the future? My CS6 will not do?

Question

Maybe there's something Adobe have said about accessing my own project files that I may have missed?   At present I can open a CS6 PP project in CS5 but without access to new CS6 features I may have used like the Warp Stabiliser etc.  That's the sort of functionality I would expect from CC PrPro - capacity to open a CC project file in CS6, but without new CC features.
My reading of the various forum discussions about this, all point out that there will be no way to access my own CC PrPro projects ever again unless I have a subscription. For instance it would not be possible to retire, cancel my CC account, and then go back a couple of years later and put together a compilation.  I would need to take out an annual subscription just to work on my own project?  Does Adobe really intend this to be the case?
Their $600 per year charge (from next year) is consistent perhaps with permanent up-grade purchases, except that with CC it seems that I will really only be renting the software.  I have been hoping for instance that Adobe would release an audio synch feature for multi-cam editing. Now that it's finally in CC however, I find I can buy it for $200 from PluralEyes to work with CS6.  Suddenly this seems an economical solution.
With Adobe emails emphatically pointing to their August 31 deadline for upgrading, I thought I would buy for sure.  However after a quick scan of the forums I thought better ask the question in the title myself.

Here is the deleted Reply from CC_merchant.  (first time I tried to send it off-forum but hasn't worked)
Once you start renting CC, you are at Adobe's mercy. There is no way out. You can't access any material you created without a valid subscription. You can't use any previous perpetual license, since there is no backward compatibility to CS6 or previous. 
If you start renting, you are putting yourself in a situation where you are being held hostage by Adobe. There is no way back!!!
Staff, of course, will deny this with very vague promises and a lot of air. Some early converters are already showing signs of the 'Stockholm Syndrome', which has been bound to happen... :((

If you have proof (screen shots, etc.) of moderators removing negative comments, please send those to me. The forums policy has been to leave negative posts in place, but it can be hard for us to police that with so many different moderators in and outside the company. 
Thanks!
