Not exactly. It is possible to import e.g. AE CS5 comps into PrPro CS5.5 project via Adobe Dynamic Link, if CS5.5 Production Premium or Master Collection installed. Since CS6 doesn't require Production Premium to benefit from Dynamic Link, but just a single application, it's possible that Dynamic Link would work in this way for PrPro CS6 as well.
However, it will be impossible to send a clip from PrPro CS6 timeline to AE CS5.5 project via Adobe Dynamic Link.
Richard M Knight: Yes, but I already have FCP Wanted to switch to Premiere for that Dynamic Link for 3 months project using Cloud. Upgrading to AE 6 just for dynamic link is to expensive for me.
