I hope it's not all small, slow straightfoward fights like those shown in the video. I like the introduction of more rpg elements like squad advancements and more skills etc.
The slow paced, small scale fights look boring compared to the first game though. Also the easy mode of squad leaders and therefore squads never being able to die is weak, I hope there's an option to disable that. It covers up poor level design and balance issues if it's a necessary feature.
It brings Cannon Fodder back to mind, it was a great feeling to have soldiers survive missions and get better weapons but when they died it was really painful, you lose that connection and interactivity with the little men on screen if you know they are immortal. In fact it seems to make the extra strategic gameplay pointless because why worry about strategy if you can just raise dead?
