Will there be new artillery units?
Yes, for example i forgot who it was given to, but either the Russians or French get an artillery unit that fires like the puckle or organ gun, except instead of firing tiny or small rounds it fires the normal rounds of cannons so you can have the power of 2-3 artillery units into 1 unit, the only con is of course reload ability and upkeep.
AI has been improved. Its still based upon the ETW AI but given a nice makeover and i saw that in my MP campaign against my opponent.
An example was during my campaign, when i allied with Venice and gave them a settlement, a french army neared one of my settlements in the middle, the Venetians would send units down to my settlement to protect it, apart from that however i can't say much though, but the AI was much more logical and willing, and no outrageous demands yet during my campaigning. AI is much more aggressive in terms of naval invasions and such as Kieran told me, expect a good fight. I surely did.
Are the campaigns Bigger?
Its so big it makes me cry, not overly big but its big enough to make a game session last quite awhile in my opinion, coupled with the beautiful environment, both on the battle map and campaign map makes it an eye candy to watch
Naval combat improvements?
Naval warships can repair itself during battle, but they have to leave the battlefield for a short while, and once the ship has been quickly repaired it will be at half health or strength, but its a nice feature to have. Damage effects and cannon trajectories as well have been improved as with of course the explosions.
Mod Tools, WHARZ MAH MOD TOOLZ
Lengthy talk, lets see if i remember, basically they will release it, i am sure they will anyways, its just, unlike Rome or medieval which burrowed on the same stuff, Empires is of course new and requires lots of nut cracking and people able to understand the codes and such before they release it (i'll expand more on this later)
Diplomacy? FIXED?
Going by the MP campaign i recently fought the AI is much more logical and willing to do things, Venice being a shining example, i didn't get the chance to explore it fully however so bleh
Negative Diplomacy, for example I want you to break relations with Britain, if not I will come over and beat you to death is a new feature. At least thats how i rememeber it when i asked about Diplomacy i may be wrong -_-
HORSIES, DRAG? RIDERS? WHAR?
As Kieran said, it will be in the game, i didn't see it however, maybe in the final release perhaps i don't know, the only thing i saw was unhorsed horsies running about, i was paying too much attention to winning the battles. (sorry)

Kieran said the rag doll physics isn't fully ragdoll, more like half, i understand that as well considering Empires isn't supposed to be made as a fully ragdoll friendly kind of game (what am i saying?)
UNIT EDITOR WHAR IZ IT?
It WILL be released shortly after the release of Napoleon, im quite sure of that as well considering how simple the program is when he explained it, so im hopeful/sure that it would be released in about a couple weeks.
EMPIRE BATTLE MAPS LOOKED BLAND, NOT ENOUGH VARIETY! YOU SUCK CA =<
Kieran explained to me quite well that there will be more of a variety, more lush forests, shrubs, valleys, rivers and cliffs are just some of the improvements that you will see in Napoleon.
Other improvements such as cool little Easter eggs of sorts and other features when your fighting a battle, say your fighting in Russia you will encounter dead frozen soldiers across the battlefield, or your fighting somewhere in Europe you will encounter dead soldiers etc. And of course much much more.
Cannon rounds will make impacts on the ground, yes you will see impact marks.
V'AT IS DIZ ATTRITION SYSTEM?
It works good and bad when Kieran explained to me about it, depending on the experience of your soldiers as well as the research technologies and buildings you build which all help in to reduce the amount of troops you lose during a campaign in Egypt or Russia for example.
THEY ABANDONED EMPIRES NO PATCHES, DAMN YOU CA
Kieran explained its a yes/no possibly we will, possibly we won't, i won't say anything more.
Units of the EAST?
Probably but most likely yes
Mod Tools for Napoleon?
It will be like empires, but you can tinker with the triggers, scripts, behaviors, but they also said they'll let us, the community tinker and fiddle with the game, though there will be cut off points onto which stuff you can alter and such. Unsure about all of this though.
Weather?
Weather plays a role, windage can affect your troops and the trajectories of your guns. Smoke drifts depending on the wind, accuracy as well
ATTACK OF THE CLONES?
No, there will be more of a variety of units as far as i can tell when i was fighting though i didn't pay much attention to there faces. Units however still wont reflect on natural effects such as mud, but there will be much more of a unit variation so yay
Special lands
Resource specific regions will add bonuses to your faction, thats all kieran said
