A simple idea here, list what you hope will be in the game, what you wish would be in the game but probably (or certainly) wont be, and what you dont want in the game, but probably will be.
To kick things off...
Hopes,
Drummers, flag/standard bearers, fifers and so forth. Preferably with animations and sound. Maybe a special Ottoman Janissary Band unit that'd act sort of like a crusader cross or one of the Italian States banner dealies.
Realistic grenadiers. From what I know, grenadiers weren't solely occupied with chucking bombs at people, even early on, they had muskets.
Accurate presentation of uniforms. I'm not calling for absolutely %100 accuracy here, but with the blog note about 'clone armies' it makes me a bit nervous that the Guard and Grenadier units are going to look sloppy, when the idea behind such units was to make every soldier look as much alike as possible. I can see non-elite formations allowing for variations in uniform (to a degree), but Gold help the Russian Lifeguard who accidentally got the wrong color button at the quartermaster.
A variety of ships. I dont want just 'sloop, frigate, Ship of the Line', I want everything from corvette upwards. 'Ship of the Line' should be split from 3rd-1st rates.
Realistic ship damage extending beyond 'LOL SHOOT THEIR SAILS WITH CHAINSHOT'. If a shot cripples a ships rudder, it shouldnt be able to steer. If the aft castle gets raked with grapeshot, there might be some coordination issues while the officers try to sort out which bits are the ex-captains bits.
Dreams,
Visible variation in unit skill. Guardsmen, grenadiers and experienced linesmen should be able to hold a pretty solid line when marching. Militia units, new conscripts and so on would probably tend to lag behind/get a bit ahead, resulting in a more ragged line. It may suprise some, but walking in a straight line at an even pace is suprisingly difficult on pretty much anything but a paved surface. :P
Likewise, the ability to deliver a volley. A highly trained unit could pretty much fire all at once, whereas a less experienced unit would deliver its volley over a space of (up to) a second or two. Maybe more.
It'd be nice if highly experienced/trained units could use the 'rank and file' system, where one rank fires, then another rank advances while it reloads, fires, and so on.
Differing morale and skill schemes based on nations. The Spanish (during the Napoleonic Wars) were famous for routing quickly when in a disadvantageous situation, but quickly reorganizing. Which is probably what kept the French from killing all of them.
The Russians, on the other hand, tended to stick to a spot until they were all dead. Their line troops were also rather famous for being truly horrible shots, while being some of the most feared troops in Europe when it came to a melee battle. After all, it was Suvurov that said, "The bullet is an idiot, the bayonet is a fine chap." (or one of the other ten thousand translations of that quote)
The British were known for having quite accurate linesmen (and, in general, for their acceptance of the rifle on a large scale before anybody else).
Seeing differences in cavalry would be nice too. Russian horses were smaller, but tended to have better endurance than the big ol' European warhorses, who were generally better on the charge, due to their superior weight.
Galleys. As much as it was the 'Age of Sail', galleys still played a huge role in the Mediterranean and Baltic. They really couldnt stand up to a Ship of the Line in open water, but in certain environments they had a distinct advantage. And the Russians and Swedes had tons of them.
Sharpshooters in Jaeger units. Historically, nations typically issued a certain number of rifles within their jaeger/skirmisher/light units, to designated sharpshooters. A few units (the British 95th Rifles probably being some of the more famous) were issued entirely with rifles, but they tended to be pretty rare in the games period.
Fears,
Bear cavalry, British rocket men, and Swedish Warrior Monks.
Naval combat ending up like IG.
Berserker AI charging infantry head on with cavalry.
Over effective cavalry. Sure, heavy cavalry was still a force to be feared, but I promise that if your unit of lifeguard curiassiers charges headlong into a formation of fresh, disciplined infantry, they're going to die. Lancer units should be the ONLY ones able to take infantry head-on, and then only by the charge/retreat scheme.
