Question about Units gfx modding

[PDX_Gorion]

Hi, I'm very happy seeing how big imperator will be and I wanted to ask for very specific thing. Will modding allow to set models for all unit types as separate entities even those which will be created by modders?
Also, will there be any tiers like in previous games so teching will change the model?
I want to get some informations since I'm planning to release mod for imperator and taking in account possibility to use unit types as trigger i will have a lot of work.

At the moment there is no plan for units having different tiers. You can define units on type and culture or even country (tag) variant
