No offense, but it helps if you know what you talk about before complaining.
The new UI is a NEW UI. The current UI is usable, but not immersive, nor pretty. It's functional at best.
They do not have animated battlefield tiles, aside from post-explosion flames, but those are not tiles per se.
The research screen is a mockup and is not actually coded and has no functionality. The current in game one is quite bland.
Battlefield motion detectors is not coded, no art is drawn and they simply do not exist. They're barely even a concept at this point.
Those are just a few parts of what they want to do with the game. Other things include art for female soldiers, for instance, which is not in the game. Also, please read the project page as it clearly states that the game is funded and slated for release this fall. The kickstarter page is PURELY to generate revenue to improve the game and make it awesome. I even wrote that in the OP. How could you miss it? I know I'm sounding like a twerp here, but seriously, King told you twice.
The money will be used to set up a studio so the coders, artists and others can work together. At the moment, they are spread out all over the world, making work slow and cumbersome. If they could set up in one location and work together, it would ease their processes a lot, making the game finished faster in addition to bringing in addition features and mechanics. It's all explained in the video.
