Yes. No. Yes it will run. No they're no compatible but AmigaOS4 has a HAL (hardware abstraction layer). Drivers will be done for the classic Amigas upgraded with a PPC card.
If the plan hasn't changed, the A4000 Cyberstorm card version will even be the first to be released. The A1200 will be the last one though but it does exist and has already been in betatest for a while.
