What variety of infantry & cavalry weapons are we likely to see in ETW and what technological development will there be during the time period.

One of the great things for me about M2TW is the large variety of troops available which stems from the great variety of weapons employed. We have axes, swords, spears, pikes, javelin, long bows, cross bows, the list goes on. I have often acquired a new unit just because they looked cool or their weapon seemed different (apparently acknowledging you have a problem is the first step in overcoming it )

Now from the artwork I've seen ETW is likely to have a colorful mix of troops, grenadiers, fusiliers, rifleman etc but their variety seems limited to their uniforms whilst they all employ similar arms, namely pike, musket, rifle, pistol, saber, lance and grenades. Am I over simplifying things here or is this all that was available?

Secondly I cant see how the unit types are going to develop its weaponry technologically. M2TW saw pikes and firearms introduced and armor develop as the time period evolves where as ETW looks as if it will only loose pikes early on and maybe have rifles become more available later. Is this the case because if so I feel I'll spend the entire game fielding armies of similar infantry and cavalry with unit variations limited to moral and experience.
