I'm quite happy with Paradox getting a head start, before we molest them with our suggestions (as good as they may be). I'm anyway convinced that "Crusades" will be one of them. I glad however that Paradox has ruled out a scifi/fantasy game. Very good move! I'll be happy with any period chosen, if done well.
Further, it's not bad to focus on "Legion" for the time being (and comparing it to Pax Romana). Also, I have yet to buy the "expansion pack" EU2, as it is not yet released in Germany. Have to see if the claims of it being such a far better game can be upheld once setting my own eyes on it.
