Okay (note that I have this information from a Belgian magazine, not from myself).
Some things might be known already, I'm just typing what's new to me.
-Apparantly you can swap technologies witho ther factions.
-Your ports can be made into fishingports (some small ships can be recruited here and they're good for your economy); into tradingports (bigger ships and very good for your economy or into Warports (well this for building those really big ships
-Operahouse is a building.
-In chapter three of 'Road to independence' Washington is one of your generals.
-Twelve factions in 'Road to independence' chapter three: Great-Britain, Spain, France, Huron, Iroqouis, Inuit and the provinces are mentioned in the article.
-Snow looks awesome, some really nice screenshots.
-Collapsing buildings look great! Again, a very nice pic.
-Some researches are different for different nations. For example: 'Firing Drill' for the Britains is something different than 'Firing Drill' for the Americans.
-Units size range from 4 to 80 men (not mentioned on what unit scale).
-Apparently you can decide how your soldiers stand in formation (eg: musketiers in one long line or in 2 lines).
-About 25 different ship types.
-AI in sea battles is pretty good.
-Almost every ship type has 3 sorts of ammo: round shots, grape shots and chain shots.
-Ottomman Empire has a special boarding ship with specialised crew for boarding.
-America has a ship type with a catapult that fires burning projectiles.
That's about it, I hope I could give you some new info.
