From a visual point of view, it's clearly taking ideas from Pandemic, which isn't a bad thing because that's a great game. Then add the XCOM factor
What I really enjoy about Pandemic is it can be learnt in 10 minutes and taught to children in minutes too, yet is none the worse for it. What I worry is XCOM will turn into yet another game requiring a 60 page tomb, the memory and intellectual capacity of a scientist comprising difficult rules, loads of look up tables and complex gameplay requiring constant reference to the manual.
Which way will this be going? I do hope it's one I can play casually with friends and family and not have to either go to a board game club or play by myself (with Arkham, I have to play 3 characters myself )
