Great job, guys, our ideas have been implemented!
Also, new covert options which (I think) you spend diplomatic capital on to gain strategic resources. It's called Black Market. (Will be a pretty neat feature once strategic resource totals are balanced on the map and within gameplay features which create more.)
Also, trade units are all amphibious now and are that way from the start, no tech required. I think they mentioned something about the Thermohaline Rudder being placed in that tech now.
EDIT: Note: they mentioned the numbers displayed in the image above are still being balanced. Also, I could be wrong, but it looks like energy and DC will be subtracted from the enemy's total, not just generated out of thin air. In the image above, each energy costs 2 remainder war points and DC costs 3 for each 1. The tech costs roughly equate to 1 science for every 1 war point you have over the enemy's total -- a much better "purchase".
Perhaps it'll be switched before release, so that you get more with your points if you buy energy or DC, but if you want techs it'll cost you a lot more. Comparing yields, I would value energy at no more than half of science -- actually, even less. Though, it should also be taken into consideration that with this energy and DC, you're not only gaining it, you're taking it away and hurting your enemy even further. With tech, you're just gaining it (which you'll use to hurt them later, haha... but the same could be said for yields generated out of thin air.)
EDIT 2: Also, I bet you're buying the science to put towards the tech, not just the tech as a whole. In the image, the two more expensive techs will cost all 740 war points. It probably has to be this way too since later on, it'll allow skirmishes to still gain portions of tech when the costs are really high. The list will probably be limited to techs they've completed which you have not.
