Eternally by subscription dependent
If you can easily find the subscription you the Adobe files yes no longer open, the projects are so gone.
Another thing to cloud
If you want a cloud should set up a home-cloud (which there now already all ready to buy), which is cheaper, safer (you have your data at home), it has extremely much space, thanks to the DSL data are easily accessible and when you're at home you have extremely fast access it anyway.
Conclusion
I would be very grateful if Adobe understands that the changes are well for many customers to the detriment and in the future offering a Creative Suite. As long as I'm waiting (especially Photoshop, there are alternatives)
