I love the new research model, it sounds great.
I was also a bit surprised that milita has seperate techs, as first I thought why not just have them use older Infantry techs, but on further though it makes a lot of sense. Most nations using Milita won't be using regular Inf and vice versa, so spiltting them shouldn't be much of an issue. Also, splitting them means you can make the Milita techs a lot cheaper than Infantry, so you don't make Inf too easy to research or Mil too hard. And if you can only afford to build Milita you won't want to waste research on Inf anyway.
It also means certain nations like, say, China can have a bonus on research and building Milita without them also getting bonuses to Inf.
The Milita conversion tech makes me wonder too. Maybe it's just an oddly named tech, it does have the same symbol as the Infanty division tech (which I'm guessing makes them cheaper to build or supply, or it could just be the next model), but maybe it means there's a new feature. Something like Mobilisation in Vic, but it provides you with a bunch of Milita (at the cost of IC?) to simulate Volksturm divisions or similar last-ditch, scraping the bottom of the manpower barrel, contortions desperate nations went through. </wild guesses>
I know it's an alpha screenshot, but how done is the overall tech screen interface? I think it'd look better with the buttons along the top either seperated a bit between types or coloured/textured. E.g Inf and armour are both land units so seperate them slightly from escorts and capitals then bombers and fighters etc.
I'd also change a few names of the top buttons:
Escorts -> Escort ships (Not a biggie though)
Capital -> Capital ships
Industry -> Industrial
Secret - > Secret weapons
Theory - > Theoretical
Land -> Land Doctrine (assuming that's what's on here. Same for Naval and Air)
It just makes them a bit more obvious and sounds better what you say "Industrial technology" than "Industry technology".
