You can open/change/save the libs and the schematics of an Altium Designer Project but the PCB has an other format. So you can use this as schematic frontend for the altium designer.
I dont think that there will be an option to open the Circuit Studio PCB files in the Altium Designer.

Effectively, I have not been able to import Altium designer PCB files into Circuit Studio, nor from CircuitStudio to Altium Designer. I hope Altium will isue a translator of some kind, since this uncompatibility seriously reduces the interest people may have in this product. Considering the cost of altium Designer support licenses, I would not be surprised if a lot of users dropped the support, still use an older version and would now choose a lighter version more suited to their needs. Importing Altium Designer files would certainly be a strong asset.

I'm one of those users, I gave up after Altium Designer 10, too much money for support compared to the level of low cost alternatives. I still use 10, it's a great program and when Altium arrives in the new reality (i.e. charge reasonable prices for upgrades), I may sign up again. But this would be a great alternative since I don't use the fancy FPGA features of Altium anyway. That is... if/when this becomes compatible.
