I just heard about this game. The review says "Looks good but in need of polish."
I did not play the original game, but based on the screenshots, it looks a bit like a mixture of the XCOM games (which I loved) and the Jagged Alliance series (which I did not like that much). I am looking forward to this - I hope it turns out to be a good mix.
As for modding - well, one can only hope. Then we start hacking
