I still dream of a day where there will mix great graphics, great physics with a true Red Baron dynamic campaign and a very LIVELY battlefield... since IL2, the graphics ate the single player gameplay and made sim TOO STERILE (no life anymore).

Red Baron wasn't dynamic. It was scripted.

Will there be a new campaign ? or is it just MP?

edit... Just read up on it again, seems it will perhaps get a campaign in future modules that will get released. I'd missed that bit!
I guess I might just give the MP stuff a miss until they come up with a SP element

PWCG will most likely be available. Based on the fact that there is a PWCG for BoX and Flying Circus will be a "Battle of" module.
Which IMO provides a much better campaign mission than the packaged Career in RoF.

I know
I played RoF to death, plus Pat's campaign generator took up a lot of my time.
Currently in a PWCG Spitfire campaign in the Kuban at the moment, and loving it!
